Every section of core the JOIDES Resolution (JR) brings up to the surface is meticulously labeled and organized with detailed stickers, wrapped in thick clear tape. Each sticker lists the expedition, site, hole, and core section. If this system fails, we also engrave the core liner itself using our onboard laser engraver, the LaserKatjie 3.0! When engraving a core liner, it is a few simple clicks to carve the plastic with the correct label.
“You used to have to hand engrave the core liner with a hand Dremel. It still hangs next to the machine, just in case,” said Zenon Mateo, Expedition 401’s Laboratory Specialist. Like most things on the JR these days, the laser engraver is a smooth running, easy to follow system.
The laser engraver does more than just label our cores, it also helps make great souvenirs. The MarkingBuilder Program allows for custom logos to be engraved onto nearly any surface. For instance, our core liners are cylinders with a 70mm diameter, but it’s also possible to engrave wooden boxes or even metal.
This expedition several of our technicians worked to engrave our expedition patch logo on extra core liner. The expedition logo is round and they are engraving on a round surface which causes warping, so adjustments to the design need to be made. The laser program has a known area that displays as a grid onto the surface you want to engrave. You can adjust power and speed which effect how deep the laser engraves the surface. It requires a lot of trial and error, but thankfully we have lots of core liner trimming to practice with.

The engraver uses a carbon dioxide laser which vaporizes a surface without damaging the structure underneath. “It’s a class 4 laser and is very dangerous if left open,” said Mateo.
The laser itself can damage your eyes, so it has built in safety glass with a green tint allowing the technicians to watch their masterpieces come to life. It also has a safety interlock system, preventing firing of the laser when the door is open.
If you have something you wish to engrave and the time to take the IODP safety courses, you can engrave nearly anything while aboard the JOIDES Resolution, such as an official IODP water bottle. Additionally, our core liner pieces create a great way to transport shrunken cups with style. Two souvenirs in one.
When I attended the OBIS Data Mobilization Workshop in the Azores (Thanks to the Air Center) this year, one observation immediately caught my attention: compared with countries such as the United States, Europe still appears surprisingly fragmented and underinvested in biodiversity data mobilization. The issue is not necessarily a lack of biodiversity research. European scientists produce enormous amounts of ecological data. The challenge is that publishing biodiversity observations into global infrastructures such as MBON/GBIF often remains an additional task rather than an integral part of funded research. In the United States, biodiversity data publication is frequently embedded in funding mechanisms and institutional mandates. Data management, curation, and dissemination seem to be recognized research activities. In much of Europe, including Denmark, researchers often mobilize data on top of their existing responsibilities, with limited dedicated funding for long-term stewardship.
I asked myself how is Denmark performing compared with its Nordic and neighboring countries?
Denmark is not lagging behind, but neither is it leading
The numbers reveal a mixed picture.
Germany clearly stands out as the regional leader, with both the highest number of datasets and the highest taxonomic coverage. Denmark has the lowest number of occurrence records and species represented among the four countries, despite having a very active biodiversity research community. What is striking is that Denmark does not fall dramatically behind in dataset numbers. Rather, the difference appears in scale and breadth. Danish datasets tend to contain fewer records and cover fewer taxa than those from Germany, Norway, and Sweden.
Different countries tell different biodiversity stories
The taxonomic breakdowns are equally revealing. Denmark should appreciate its fish and birds’ activists. Large portions of the records belong to Gadidae (cod family), Clupeidae (herring family), Laridae (gulls), and other marine vertebrates. This reflects Denmark’s historical strengths in fisheries monitoring, marine ecology, and seabird observations. However, many invertebrate groups, microorganisms, and less visible components of biodiversity remain comparatively underrepresented in global data sets despite active programs like national Program like MONIS.
Norway shows stronger contributions from invertebrate sides such as polychaetes, bivalves, copepods, and marine benthic fauna. The Norwegian data landscape appears heavily influenced by aquaculture sectores, long-term marine monitoring programs and offshore environmental surveys. There is greater representation of marine invertebrates, which are often critical indicators of ecosystem change.
What stood out in Sweden’s data profile is the relatively large contribution from copepods, diatoms, dinoflagellates, and macroalgae. These groups are often overlooked in biodiversity databases because they require specialized expertise and monitoring programs. Sweden’s contribution suggests sustained investment in aquatic ecosystem monitoring beyond commercially important species. Well done Sweden!
Germany’s profile appears the most diverse. While fish and vertebrates remain important, there are strong contributions from polychaete worms, molluscs, arthropods, plankton in general term and benthic organisms. Germany not only contributes more records but also appears to mobilize a wider variety of biodiversity data types. You made me proud Germany 
The real gap may be invisible biodiversity
One lesson from the workshop was that biodiversity databases often reflect what is easiest to observe, identify, and fund. Fish, birds, and mammals are well represented almost everywhere. The groups that drive ecosystem processes, such as jellyfish, zooplankton, benthic invertebrates, phytoplankton, and microbial communities, remain far less visible. This is particularly relevant for marine ecosystems. Some of the most important ecological changes currently occurring in our seas involve gelatinous zooplankton, plankton communities, and benthic assemblages, yet these groups remain underrepresented in many biodiversity repositories. For someone working with jellyfish and marine food webs, this raises an important question:
Are we documenting the biodiversity that is easiest to count, or the biodiversity that is most important for understanding ecosystem change?
This fall, Ocean Conservancy is celebrating its 41st annual International Coastal Cleanup® (ICC), once again bringing together volunteers to protect the beaches and waterways we all love. Ocean Conservancy recently hosted flagship events in Long Beach and Washington, D.C. that celebrated this global movement close to home.
Over the past four decades, nearly 20 million volunteers have rolled up their sleeves to remove more than 405 million pounds of trash from beaches and waterways around the world. And their impact extends far beyond what they collect. ICC volunteers have documented nearly 440 million individual items, creating the world’s largest marine debris database and providing invaluable information that helps Ocean Conservancy and others better understand—and tackle—ocean plastic pollution.
This year’s celebration continued that incredible legacy. At Alamitos Beach in Southern California, more than 150 volunteers gathered on September 19 and removed 1,109 pounds of trash, alongside members of Team USA Artistic Swimming and Olympic and Paralympic athletes. In Washington, D.C., 439 volunteers gathered on September 26 to remove 2,182 pounds of trash from Anacostia Park along the Anacostia River.
“I am so grateful to all of the volunteers who came out today for our ocean—and every volunteer who has made the last 41 years of impact possible,” said Ocean Conservancy’s Senior Director of Conservation Cleanups, Allison Schutes. “Every piece of plastic collected helps protect marine animals and habitats and contributes to research and advocacy.”
And the impact doesn’t stop when the cleanup ends. During International Coastal Cleanup events, volunteers do more than remove trash: They document what they find, helping build a clearer picture of the plastic pollution threatening our waterways and wildlife. Through the Clean Swell® app or paper data sheets, ICC volunteers contribute to Ocean Conservancy’s online, open-access database, the world’s largest repository of marine debris data. These records help scientists, conservation groups and governments understand pollution trends and identify solutions.
That data can also drive meaningful policy change. ICC data were recently used in a peer-reviewed study showing that plastic bag bans lead to reduced plastic bag pollution. The data have also helped advance policies ranging from California’s SB 54 to Florida’s balloon release ban and the federal Farewell to Foam Act. From a neighborhood cleanup to statewide action, every piece of documented trash helps build the evidence needed to tackle plastic pollution at its source.
