You never really think too much about time unless you are late, planning an event, or even setting your alarm clock. It generally is understood that it exists and we, as a society, keep track of it through clocks, watches, conversations, and agendas.
When you get accepted to sail on the JOIDES Resolution, you understand that you are going to work 12 hours under the time zone the ship is chosen to follow. However, time starts to become more and more relative the longer you are on the ship.
The first moment where you notice that the way you interact with time is different to the way you interact with it on land is when the only greeting you hear is “Good morning!”. The ship operates 24/7, which means that there are 4 different shifts for the 118 crew members to work. Your morning can be midnight, 6pm, 6am, or midday, and thus anytime you see someone for the first time that day you greet them with good morning.
This is not initially detrimental to your concept of time, but compound it with the fact that your 12 hour shift isn’t wholly during daylight hours. While the midnight to midday or midday to midnight both are split almost in half by daytime and night time, the 6pm to 6am does not experience that. The 6pm to 6am shift wakes up to night as their morning, and works through their shift as it spans across two calendar days. Their today is tomorrow as well, and they go to bed after sunrise making their tomorrow start tonight. The most similar to land time is the 6am to 6pm shift, but very rarely do more than 4 people get to work that shift, but even then time is still a little wonky since you still interact with onshore colleagues that are not in the same timezone as you.
Timezones become a regular part of how you think because you have onshore family, friends, and work colleagues that are in a different time zone from you. Plus, shipboard computers are always at UTC but shipboard clocks and watches are on the current timezone we are sailing in. For instance, we are sailing in the Italian time zone, UTC + 1. Add in the fact that as the outreach officer I have to schedule ship to shore broadcasts for a global audience, I have to discern what time zone the 3pm that someone wants to book an appointment is in compared to mine. The mental gymnastics become especially interesting when the time zone differences leads to it being my tomorrow but their evening. For instance, 7 pm EST for someone in New York, USA on March 22 is the ship’s 12am March 23.
As our shifts extend into different days, being able to talk about what day it is becomes even harder. A lot of times we just say “two days from now” or “ when you wake up next” instead of identifying the actual day as Monday or Friday. This very likely is heightened by the fact that a lot of our day is monotonous, once described as ground hog day. Wake up – eat – work- eat- work – eat- social time- sleep- REPEAT. Give or take the sunset or sunrise.
I am not the only one that experiences time as a weird social construct when on the ship, it is a shared by my crew members.
Brandon, one of the physical properties specialists on board, mentioned that the only way he knows it was the weekend was due to the fact that he gets less emails than usual. Tori, one of the Paleomagnetists on board, pointed out that the language we use to identify meal time is even lost. When trying to invite someone to take a break for lunch, it could be your first meal but their second meal and the kitchen’s third meal cooked that day, and thus you are left to say “Meal time?”. Don’t forget that the only crew members that get breakfast food like eggs or oatmeal for their first meal is the 6am to 6pm shift, which is not ideal for Brandon who really enjoys some bacon in the morning. So you can’t really use the kind of food you have to develop an understanding of time passing.
As much as time, when on the ship, is endless or a black hole or far from reality, it is cherished by the crew members. We create unique bonds of friendship, and find ways to provide variability as the days drone on. During expedition 402 we had a hot wing competition, wellness wednesday movie night, a talent show, and more. We make do with time on the ship, even if we are confused about what day or time it is.
Welcome to the M219 ocean blog!
Here, we will share updates and stories about the scientific work taking place during this research expedition. We also hope to offer a glimpse into daily life and work at sea.
For many members of the scientific party, this is their first time aboard METEOR. It will also be their last, as METEOR is embarking on its final voyage before retiring from service as a German research vessel after more than 40 years at sea. Over the course of its distinguished career, METEOR has travelled more than 1.7 million nautical miles, which is equivalent to more than 8 times the distance between the Earth and the Moon. Throughout those decades the vessel has supported countless scientific discoveries and generations of marine scientists. We are very grateful and honored to be part of the final chapter of this remarkable ship’s history and to accompany her on the last few thousand miles of her legendary journey.
The scientific program of this cruise focuses on long-term observations of ocean currents off the coast of Brazil and at the equator, as well as interdisciplinary measurements near the Cape Verde Islands. At all these sites, GEOMAR has maintained observational programs for the past 10 to 20 years. Over the next four weeks, we will introduce these regions and the measurements carried out there in more detail. But first, let’s look at what happened in Brazil before the cruise began.
On Thursday, May 28, many of the scientists and students left the hotel early in the morning to attend a seminar at the Universidade Federal de Pernambuco (UFPE), celebrating the long-standing scientific collaboration between Brazil and Germany.
The seminar was opened by Prof. Dr. Marius Müller, a former student at GEOMAR and now a professor for biological oceanography at UFPE. These meetings have become a valued tradition, having been organized for more than 20 years by now. This year marked the 9th edition of the seminar since its inception over 20 years ago.
A total of 8 scientists and students from Brazil, Germany, and the U.S. presented their research on various aspects of the tropical Atlantic Ocean. We would like to thank Marius Müller, Doris Veleda and all the Brazilian scientists and students who helped organize the seminar and provided such a warm welcome. We greatly enjoyed the exchange of ideas and look forward to celebrating the 10th seminar in the years to come.
After the seminar we returned to the hotel, but there was little time to rest. Later that same day, the captain of METEOR and the German Consul General in Recife hosted a reception aboard METEOR in the Port of Recife.
The event brought together members of the scientific party, representatives of local institutions, and guests from the Brazilian and German scientific communities. It provided an excellent opportunity to celebrate the long-standing partnership between the two countries.
On Friday, May 29, the scientific party finally boarded METEOR. There was little time to settle into our cabins and workspaces, as preparations for departure were already in full swing. We left the Port of Recife as soon as possible and at around 1pm METEOR set sail and began the final voyage of her remarkable career.
About 12 hours after leaving port, we arrived at our first station. Thanks to the dedicated efforts of technical and scientific teams, all instruments had been installed and prepared in time for the start of operations. This station marked the beginning of our observational program off the coast of Brazil, which includes the deployment and recovery of tall moorings as well as CTD measurements. An intensive first week lies ahead, with a demanding schedule of measurements and mooring operations. After months of planning and preparation, everyone is excited to finally begin the scientific work and make the most of the final weeks aboard METEOR.
There are more than 2,000 species of gobies (Gobiidae) known to science today, making them the largest family of fish in the ocean. But these small creatures are far more complex and essential to marine ecosystems than first meets the eye. Found all around the world in brackish, fresh and salt water in tropical and subtropical regions, they are an astonishingly diverse group of fish with several curious characteristics that set them apart.
Most gobies are quite small and don’t usually measure more than six inches long. Measuring just about eight millimeters long, the dwarf pygmy goby (Trimmatom nanus) is not only the tiniest goby known to science but also one of the smallest of all fish species in the world.
Primarily bottom-dwellers, gobies are known to be excellent foragers and have evolved expert burrowing behaviors over time. As they sift around looking for food like copepods, seaworms and tiny crustaceans, their movement helps to aerate sediment and keep algae in check. Some are even known to be “cleaner fish,” snacking on parasites they remove off larger creatures. It’s like a spa day for the animal being cleaned and a choose-your-own-adventure buffet for the gobies. Studies also show that cleaner goby activity is largely tied to the microbial health of coral reefs, showcasing that even the tiniest of species are essential to functioning marine ecosystems.
Gobies have some unique aspects to their anatomy, too. First, their fused pelvic fins are designed to help them form a strong suction cup to perch on coral reefs, rocks and other ocean terrain amidst turbulent currents. Some freshwater species are even known to use this suction to climb waterfalls. It may come as no surprise then that gobies are cousins to mudskippers, animals known to “walk” through mud. There are more species-specific features that set certain gobies apart. From the use of bioluminescence to symbiotic relationships with shrimp, the adaptations within the goby family are truly wide-ranging. Some species have even been found to use marine terrain memorization to navigate back to the tide pools where they were born. Isn’t nature mind-blowing sometimes?

Gobies have equally complex and varied behaviors. Male gobies are infamous for being territorial protectors of their nests. Many larger males are known as “guarders;” these hopeful fish make careful nests to attract a mate, and once fertilization occurs, guarders will remain diligently near the nests to keep eggs safe. However, there’s another type of male goby that complicates this dynamic. These other males are known as “sneaker gobies” and are called that for one reason: They’re sneaky! If guarder gobies aren’t careful, sneakers can creep into the nest, fertilize some of the eggs and quickly escape. As if on an underwater episode of Maury, guarder males who aren’t careful could end up unknowingly babysitting little gobies that aren’t their actual offspring.
Gobies serve as indicators of ecological health and are essential to keeping delicate food webs in check. Unfortunately, many changes in our ocean threaten their ability to survive and thrive today. Coral bleaching and degradation endanger the health of one of their key habitats, and a combination of warming waters and coastal development can make it difficult for both juvenile and adult gobies to survive and thrive.
Healthy gobies mean a healthy ocean. Their essential role in marine ecosystems demonstrates that even the tiniest creatures play a major role in helping hold together the beautiful yet fragile habitats that make up our beloved ocean. Visit Ocean Conservancy’s Action Center and join the movement to protect our blue planet today and for years to come—from the tiniest goby to the largest whales, our ocean is counting on us.

Recently, you may have heard about something called “El Niño.” But what exactly is El Niño and its sibling “La Niña”? Why do these terms seem to emerge from the depths of the scientific community and drop into popular vocabulary every few years? And how are they connected to extreme weather and our ocean?
What Are El Niño and La Niña?
El Niño and La Niña are part of a natural climate pattern in the tropical Pacific called the El Niño-Southern Oscillation, or ENSO. These two phases are different sides of the same coin, creating equally extreme shifts in temperature and air pressure.
El Niño occurs when surface water in the equatorial Pacific becomes warmer than average and easterly winds weaken. La Niña is the opposite: cooler-than-normal sea surface temperatures and stronger easterly winds. ENSO cycles can last up to seven years. El Niño and La Niña significantly impact weather patterns in all corners of the globe, often leading to more extreme weather, storm frequency and intensity.
A strong El Niño can cause flooding in some regions and drought, heat waves and wildfires in others. It often causes crop losses, coral bleaching and marine die-offs due to unusually warm ocean temperatures. El Niño tends to suppress Atlantic hurricane activity, though it increases the risk of heavy precipitation and harm to fisheries elsewhere. In the Northern Hemisphere, El Niño typically builds between March and June, peaks in December, and weakens by February.
La Niña, by contrast, often fuels an active Atlantic hurricane season and increases tornado frequency across the southern United States. Like El Niño, it builds in spring and peaks around December.

Predicting ENSO
In 1923, the physicist Sir Gilbert Walker discovered the “Southern Oscillation,” or large-scale changes in sea level pressure across the tropical Pacific. However, it wasn’t until the late 1960s that the metorologist Jacob Bjerknes found that the changes in the ocean and the atmosphere were connected, and the hybrid term “ENSO” was born. In 1974, researchers at Oregon State University attempted to predict ENSO for the first time.
Modeling has greatly advanced since the early days. Today, scientists at the National Oceanic and Atmospheric Administration (NOAA) issue regular predictions about ENSO, which are now more accurate than ever.
NOAA gives a one-in-four chance that an El Niño could reach “very strong” intensity later in 2026, qualifying it as a “super El Niño.” This threshold has been crossed only a handful of times in recorded history, each triggering droughts, floods and record temperatures across multiple continents. NOAA’s data and models deliver life-saving early warning forecasts, like that of the predicted super El Niño, which allow communities to better prepare for and respond to extreme weather events.
Take Action
Every American, regardless of where they live, depends on NOAA’s scientists and professionals, whose work spans from the ocean floor to the far reaches of space. Unfortunately, NOAA is under threat. The Trump administration has proposed billions of dollars in cuts to the agency, which could weaken weather forecasting, disrupt fisheries management and stall critical ocean research, putting American lives and global scientific leadership at risk.
Ocean Conservancy is committed to working with NOAA to keep the public informed on climate and ocean science. We all benefit from a healthier ocean, and investing in research is the most effective way to restore ocean health and reduce the impact of severe weather events caused by El Niño and La Niña. Our ocean is not partisan, and protecting it requires all hands on deck and all sides of the aisle. Now, it’s more important than ever to demand that members of Congress prioritize our ocean. Add your name now.
