Nayyir Ransome builds relationships between the government and the people it serves to support the ocean. As Senior Analyst with Ocean Conservancy, Nayyir sees the power of small, incremental steps that lead to big impacts for people and waterways.
“I want to encourage people to start where they are. Start with your friends, your church group, your classroom”, Nayyir shared.
Nayyir started advocacy work when they were young, joining the Campfire Youth Legislature as a seventh-grade student in Broadmoor Middle School in East Baton Rouge Parish School System, a school that was closed in 2019. “I was one of the youngest people in the room. The bill that I proposed didn’t even make it out of committee. So, when it was time to come together on the floor and vote on all the bills that came out of committee, I decided that I was going to speak on every single bill that hit the floor, literally, all of them. I ended up winning Outstanding Legislator that year. This honor is given only to one legislator out of almost 500 young people from across the state. I still have the medal. I keep it on my desk lamp with all my other conference tags and medals. It reminds me how much impact a person simply speaking up can have. Whether or not the vote goes your way at that moment, someone is still listening.”
Nayyir got involved in Youth Legislature at a time in Baton Rouge, Louisiana, when many students were feeling unheard, anxious and facing physical displacement after Hurricane Katrina.
Remembering the day Hurricane Katrina landed
On August 29th, 2005, Hurricane Katrina made landfall in New Orleans. At least 1,900 people were killed in the storm and, due to medical and infrastructure complications, post-storm. The devastation of one of the deadliest hurricane seasons in United States history forced 650,000 survivors from their homes—some were never able to return.
“We were out of school for two weeks. Compared to New Orleans where many schools closed for months and others shut their doors permanently, this felt like a privilege. When we went back to school, there were 200 more students in the building. Many families from New Orleans were forced to move to temporary housing in Baton Rouge. Our school was one of many that saw a large influx of students from New Orleans where many schools were unable to reopen due to Katrina. There wasn’t enough space, services or support to handle that, and it became a tense environment for all of us.”
Nayyir’s family moved to Baton Rouge just one year before the storm. Coming from Philadelphia, one of the largest metropolitan cities in the country, Nayyir experienced an intense culture shock when adjusting to life in open-air, sea-centric Southern Louisiana. Nayyir reflected on the contrast of towering buildings and lightning-fast train transport to kids catching mudbugs from the crawfish mounds in the drainage ditches, designed to channel storm water, along roads without sidewalks.
“When I started participating in Camp Fire USA’s Youth Legislature program, I felt intimidated. It was a strange experience, grappling with my own sense of displacement while watching other kids being displaced on such a large scale due to Hurricane Katrina. I wasn’t from the area, but I was there, and I did understand how it felt to be pushed out, to feel discarded.”
New Orleans has a culture unlike any other place in the world, and this rich weaving of languages, ethnicities and histories creates an unshakable strength that still stands today. Yet, the crippling impacts of Hurricane Katrina can be traced through the yet-to-be-rebuilt homes in the Lower Ninth Ward and the reality of long-term health consequences and economic instability for many residents, even now, 20 years after the storm.
Hurricane detection is better than ever, thanks to NOAA
In 2005, the best hurricane detection science provided around a 48-hour warning. The people of New Orleans had less than 24 hours from the time the mandatory evacuation order was issued to when water began to spill over one of the levees.
When Hurricane Katrina developed into a Category 3 storm, receded and then reformed as a Category 5 storm, scientists, local officials and communities scrambled to keep up and spread information quickly.
“We didn’t know what was happening in New Orleans for three days. People with friends and family there were starting to panic.”
Now, thanks to the steady, decades-long efforts of organizations like the National Oceanic and Atmospheric Administration (NOAA), current predictive technologies can provide up to five days warning of extreme weather—enough time potentially to prevent storms from having the same catastrophic impact as Katrina. Yet, the question remains, ”Will we continue funding the hurricane forecasting systems we know are protecting our communities?”
Tell Congress to Protect NOAA Today
Take action to ensure Congress stands up for NOAA, demanding the agency be fully funded and fully staffed.
Understanding NOAA’s vital role during storm season
It might not be clear what NOAA does during hurricane season because much of their work is behind the scenes. The National Weather Service sits under NOAA, and NOAA scientists and professionals are key players in many of the long-term conservation measures, research and technology that prevent the most dire consequences of extreme weather. Their work includes projects that we may not think of as disaster preparedness and resilience, such as coastal restoration initiatives.
NOAA uses a variety of scientific instruments on crafts such as planes, saildrones and gliders to gather data from inside hurricanes. Long term ocean observations contribute to hurricane and weather models. This hurricane season we have an opportunity to speak up about the proposed cuts to NOAA and the vital resources we would lose if these budget changes are approved by Congress. Continuing to fund NOAA is one way to ensure ongoing improvements to weather forecasting, honor those lost to Hurricane Katrina and, in the aftermath, support the people of New Orleans today, as they rebuild and heal.
We can all speak up for life-saving hurricane detection and research
As storm seasons intensify, we need faster, more accurate weather prediction and storm detection more than ever. NOAA is America’s first line of defense against the deadliest impacts of natural disasters on our communities. Yet, NOAA’s funding is facing major cuts that, if enacted, will result in lives lost. We need to keep moving forward keeping in mind and heart the nearly 2,000 people who lost their lives during Katrina, the thousands more New Orleanians who lost their land and legacies, and the hundreds of thousands of people who are impacted by deadly storms in the United States each year.
Looking back, Nayyir can see how these experiences growing up in post-Katrina Louisiana shaped their advocacy and approach to community organizing.
“My time in Southeast Louisiana taught me a lot about people-centered advocacy. Even if we haven’t experienced something at its most extreme, we can find a way to understand the root of it by looking at our lives and the places we live. Ocean Conservancy has helped me to grow in how and why we must work across government agencies and lines to protect our ocean and the people who rely on it.”
Ocean Conservancy works alongside NOAA as a science-led advocacy organization mobilizing federal, state and local action for our ocean. Every investment in NOAA translates into vital seconds, hours and days of response time for communities when hurricane season strikes. The more data we can collect and use to predict the behavior and patterns of storms, the better we can respond and prevent tragedies.
Each year, storm season is intensifying from climate change—and not just on our coasts. Communities throughout the U.S. are affected by hurricanes and floods that threaten lives and livelihoods. We all rely on NOAA’s vital research and tools for weather prediction and extreme weather warnings. These services are a lifeline we cannot afford to lose.
Call on your Congress members today and insist they support full funding and operation of NOAA.

After a slight delay of the Maria S. Merian caused by late-arriving containers our research cruise MSM142 finally got underway. By last Tuesday (24.03.2026), the full scientific team had arrived in Nuuk, the capital of Greenland, and the ship reached port on Wednesday (25.03.2026) morning. That same day, scientists and technicians moved on board and immediately began preparations, assembling and testing our instruments. Although the mornings on Wednesday and Thursday were grey and overcast, the afternoons cleared up beautifully. This gave us valuable time to organize equipment on deck and store empty boxes back into the containers before departure.
Given the forecast of harsh conditions outside the fjord, we carried out the mandatory safety drill while still in harbour. This included practicing emergency procedures and boarding the lifeboat. After completing border control, we were finally ready to leave Nuuk. We set sail on March 27th, heading into the Labrador Sea to begin our mission. Even before starting scientific operations, we tested the setup for deploying our gliders without releasing them during the transit out of the fjord. Once we reached open waters, we were met by high waves the following morning. For some on board, this was their first experience under such rough sea conditions. Seasickness quickly became a challenge for a few, while scientific work had to be temporarily postponed due to the strong winds and sea conditions. Together with the crew, we discussed how best to adapt our measurement plans to the given weather conditions. On March 29th, we were finally able to begin our scientific program with the first CTD deployment. A CTD is an instrument used to measure conductivity, temperature, and depth, which are key parameters for understanding ocean structure.
During the following night, we continued with additional CTD stations and successfully recovered two moorings: DSOW 3 and DSOW 4, located south of Greenland. These moorings carry instruments at various depths that measure velocity, temperature, and salinity. DSOW 4 was redeployed on the same day, while DSOW 3 followed the next day. In addition, the bottles attached to the CTD’s rosette can be used to collect water samples from any desired depth. These samples can be used, for example, to determine the oxygen content, nutrient levels, and organic matter.
Both are part of the OSNAP array, a network of moorings spanning the subpolar North Atlantic. On these moorings are a few instruments, for example microcats which measure temperature, pressure and salinity.
We then conducted around 25 CTD stations spaced approximately 3 nautical miles apart across an Irminger ring identified from satellite data. This high-resolution sampling was necessary to capture the structure of an Irminger Ring, which had a radius of about 12 km wide.
The days leading up to April 2nd were marked by very rough weather conditions. Life on board became both challenging and, at times, unintentionally entertaining sliding chairs were not uncommon. During the night from April 1st to April 2nd, winds reached 11 Beaufort with gusts up to 65 knots, forcing us to pause our measurements. Fortunately, conditions improved by morning, allowing us to resume our work. As well as with the help of the crew we had to adapt to the harsh weather conditions to continue our scientific work. On the 3rd of April, we were able to deploy a few gliders and one float. An ocean glider is an autonomous underwater Vehicle, which you can steer remotely and send to different locations, while it is measuring oceanographic key parameters.
This research cruise focuses on understanding small-scale processes in the ocean and their connection to the spring bloom, an essential phase in marine ecosystem in subpolar regions. Despite the challenging start, we have already gathered valuable data and look forward to the weeks ahead in the Labrador Sea.
Despite their dramatic name, false killer whales aren’t an orca species. These animals are dolphins—members of the same extended family as the iconic “killer whale” (Orcinus orca). Compared to their namesake counterparts, these marine mammals are far less well-known than our ocean’s iconic orcas.
Let’s dive in and take a closer look at false killer whales—one of the ocean’s most social, yet lesser-known dolphin species.
Appearance and anatomy
False killer whales (Pseudorca crassidens) are among the largest members of the dolphin family (Delphinidae). Adults can grow up to 20 feet long and weigh between 1,500 and 3,000 pounds, though some individuals have been recorded weighing even more. For comparison, that’s roughly double the size of a bottlenose dolphin—and slightly larger than a typical sedan.
These animals are incredibly powerful swimmers with long, torpedo-shaped bodies that help them move efficiently through the open ocean in search of prey. Their skull structure is what earned them their name, as their head shape closely resembles that of orcas. With broad, rounded heads, muscular jaws and large cone-shaped teeth, early scientists were fascinated by the similarities between these two marine mammal species.
Although their heads may look somewhat like those of orcas, there are several ways to distinguish false killer whales from their larger namesake counterparts.
One of the most noticeable differences has to do with their coloration. While orcas are known for their iconic black-and-white pattern with paler underbellies, alternatively, false killer whales are typically a uniform dark gray to black in color—almost as if a small orca decided to roll around in the dirt. If you’ve ever seen the animated Disney classic 101 Dalmatians, the difference is a bit like when the puppies roll in soot to disguise themselves as labradors instead of showing their usual black-and-white spots.
Their teeth also present a differentiator. The scientific name Pseudorca crassidens translates almost literally to “thick-toothed false orca,” a nod to their sturdy, cone-shaped teeth that help these animals capture prey. Orcas tend to have more robust, bulbous heads, while false killer whales appear slightly narrower and more streamlined.
Behavior and diet
False killer whales are both highly efficient hunters and deeply social animals. It’s not unusual to see them hunting together both in small pods and larger groups as they pursue prey like fish and squid.
Scientists have even observed false killer whales sharing food with each other, a behavior that is very unusual for marine mammals. While some dolphin and whale species work together to pursue prey, they rarely actively share food. The sharing of food among false killer whales spotlights the strong social bonds within their pods. Researchers believe these tight-knit social connections help false killer whales thrive in offshore environments where they’re always on the move.
Maintaining these close bonds and coordinating successful hunts requires constant effective communication, and this is where false killer whales excel. Like other dolphins, they produce a variety of sounds like whistles and clicks to stay connected with their pod and locate prey using echolocation. In the deep offshore waters where they live, sound often becomes more important than sight, since sound travels much farther underwater than light.
Where they live
False killer whales are highly migratory and travel long distances throughout tropical and subtropical waters around the world. They prefer deeper waters far offshore, and this pelagic lifestyle can make them more difficult for scientists to study than many coastal dolphin species.
However, there are a few places where researchers have been able to learn more about them—including the waters surrounding the Hawaiian Islands.
Scientists have identified three distinct groups of false killer whales in and around Hawaii, but one well-studied group stays close to the main Hawaiian Islands year-round. Unfortunately, researchers estimate that only about 140 individuals remained in 2022, with populations expected to decline without action to protect them. This is exactly why this group is listed as endangered under the U.S. Endangered Species Act and is considered one of the most vulnerable marine mammal populations in U.S. waters.

Current threats to survival
False killer whales are currently listed as Near Threatened on the IUCN Red List. From climate change-induced ocean acidification and harmful algal blooms to marine debris and fishing bycatch, false killer whales face the same mounting pressures that are impacting marine ecosystems around the world. As their prey becomes scarce due to increasing threats, populations of top predators like these decline, serving as a powerful signal that the ocean’s overall health is in critical need of protection.
Here at Ocean Conservancy, we’re working daily to confront these threats head-on and protect the ecosystems and wildlife we all cherish so dearly. But we can’t do it without you. Support from ocean lovers is what powers our work to protect our ocean, and right now, our planet needs all the help it can get. Visit Ocean Conservancy’s Action Center today and join our movement to create a better future for our ocean, forever and for everyone.

A lot has happened in the meantime: I became an Associate Professor at the University of Southern Denmark, we all lived through the Corona period, then slowly adjusted to the post‑pandemic stability, only to find ourselves again in turbulent political times. I am now affiliated with the Marine Research Center in Kerteminde, a beautiful coastal town on the island of Fyn. My plan is to share small updates on my research and activities every now and then. So let’s start with yesterday’s sampling trip for benthic phytoplankton, carried out by my colleague, Prof. Kazumasa Oguri. The sampling will help prepare for the first‑semester bachelor students who will join his small but fascinating project. This project is all about the benthic diatoms that form dense, photosynthetic communities on tidal‑flat sediments. Their daytime oxygen production enriches the sediment surface and allows oxygen to penetrate deeper, supporting diverse organisms that rely on aerobic respiration. The project will explore how oxygen distribution and oxygen production/consumption in sediments change under different light conditions (day, night, sunrise/sunset). The team will incubate benthic diatom communities in jars and measure oxygen profiles using an oxygen imaging system under controlled light regimes.
Yesterday, we visited several potential sampling sites where students can carry out their fieldwork. I encourage all PIs in our group to define at least one small project related to Kerteminde Fjord, where our laboratories are located. Over time, I hope we can build a more integrated dataset describing the marine and coastal ecosystems of the area.
Another activity currently in preparation is a project on marine invasive species in Kerteminde, which will feed into a course I will run in July and a master’s thesis project. More will come later.
Let’s hope for a more continuous blog from here on, keeping track of our activities, with or without jellyfish!
