A shell of a ride: Pteropod survival through past mass extinction events and insights into present climate change
By looking at DNA and fossils of pelagic sea snails, Dr. Peijnenburg and colleagues are beginning to understand how this group has withstood past climate change, and how they may survive current ocean acidification. Gabrielle StedmanI am currently a 3rd year PhD student in Biological Oceanography at the University of Hawai‘i at Manoa. I use […]
It’s a match! Cod do best when paired with copepods
What makes or breaks the young life of a cod? Maybe it’s food. Researchers investigated the overlap between young cod and a fatty copepod in the Norwegian-Barents Sea. Kristin HuizengaI am a PhD student studying Biological Oceanography at the University of Rhode Island Graduate School of Oceanography. My interests are in food webs, ecology, and the […]
What your poop says about your diet: Iron in the ocean is controlled by zooplankton diet and poop
Have you ever had weird colored poop? Just like your poop can tell you what you’ve been eating lately, zooplankton poop can tell you what they’ve been feeding on. Iron in zooplankton poop is used as a nutrient by phytoplankton to boost their growth and absorb more carbon dioxide from the atmosphere. Therefore, understanding how […]
Catch prey while the sun shines – Herring grow bigger when they can see their food
It is a truth universally acknowledged, that a sea creature in possession of a home in higher latitudes (further from the equator), must (on average) possess more size than its mid latitude neighbors. But why should high latitude fish be in possession of such a good fortune? Kristin HuizengaI am a PhD student studying Biological […]
I like to move it, move it: Krill boogie down all year
Krill, the tiny organisms that feed the Southern Ocean, have long been thought to be pretty mellow in the winter. As it turns out, it is quite the party down there year around! Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging focuses […]
Wandering copepods can’t find their way home in acidic oceans
Journal source: Smith, J. N., C. Richter, K. Fabricius, and A. Cornils. 2017. Pontellid copepods affected by ocean acidification: A field study at natural CO2 seeps. PLoS ONE 12 doi: https://doi.org/10.1371/journal.pone.0175663. Introduction Ocean acidification (OA for short) is a topic that seems to be receiving increased attention, and if you’ve scrolled through some recent Oceanbites posts, […]
Connecting production to glacial meltwater
As sea-ice disappears, many scientists predict that primary production will increase in high latitude regions. A Danish group adds some nuance to this prediction based on a recent study off the coast of Greenland. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for Underwater Imaging […]
Mucus flux and other amazing discoveries with underwater cameras
Scientists have been taking pictures underwater since the turn of the 19th century. But only recently have researchers and engineers started designing special systems to answer some of the most vexing questions in oceanography. Just last week, a group from MBARI published their findings from one such instrument about zooplankton mucus. Eric OrensteinEric is a […]
Penguins can rock their bodies without eating high trophic level prey
Prey of a higher trophic level does not necessarily translate to a higher body mass in rockhopper penguins. Read more to find out why! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in Iceland, and am currently working at the Smithsonian Institution’s National Museum of Natural History […]
Herds of sea monkeys help scientists understand the role of diel vertical migration in ocean mixing
Article: Monica M. Wilhelmus and John O. Dabiri. Observations of large-scale fluid transport by laser-guided plankton aggregations. Physics of Fluids, September 30, 2014 DOI: 10.1063/1.4895655 Background Every day, as the sun sets, hundreds and thousands of individual zooplankton begin to swim up from deep waters to the surface. This daily migration is known as diel vertical migration and […]
