Turbulence and Bioluminescence
If you’ve ever seen crashing waves glowing blue, you’ve been treated to bioluminescence. Although many creatures can bioluminesce, tiny dinoflagellates–a type of marine phytoplankton–are one of the easiest to spot. These microscopic organisms create a flash of light in response to viscous stresses. Their response to flow-induced stresses is so robust that they can be used to visualize stress fields.
In a new study, researchers explored how turbulence affects the dinoflagellate’s luminescence. They mathematically modeled the dinoflagellate as an elastic dumbbell that emitted light based on its extent and rate of deformation. Then they explored how this model dinoflagellate behaved in different types of turbulent flows. They found that the fluctuations and intermittency of turbulent flows both encouraged the radiant displays. (Image credit: T. McKinnon; research credit: P. Kumar and J. Picardo)

Chlorophyll Eddies
Instruments aboard NASA’s PACE mission are able to distinguish far more about phytoplankton blooms than previous satellites. This image shows chlorophyll concentrations in the Norwegian Sea in July 2025. Chlorophyll acts as a proxy for phytoplankton, which produce the chemical as they process sunlight into food and oxygen.
Despite their microscopic size, phytoplankton have enormous collective effects. Scientists estimate that phytoplankton produce as much as half of the Earth’s oxygen in addition to helping transport carbon dioxide from the atmosphere into the deep ocean. They are also the foundation of the marine food web, feeding nearly all life in the ocean. (Image credit: W. Liang; via NASA Earth Observatory)

Warming seas threaten key #phytoplankton species that fuels the #foodweb, study finds
“These are #keystonespecies — very important ones,” said François Ribalet, a research associate professor at the University of Washington’s School of #Oceanography and the study’s lead author. “And when a keystone species decreases in abundance, it always has consequences on #ecology and #biodiversity. The food web is going to change.”

Planktonart droht starker Schwund
Er ist ein extrem wichtiger Sauerstoffproduzent und sowohl der kleinste als auch der am häufigsten vorkommende photosynthetische Organismus der Erde: das #Phytoplankton #Prochlorococcus. Eine Studie zeigt nun, dass das #Bakterium empfindlicher auf hohe Temperaturen reagiert als bisher gedacht.
Die ökologische Bedeutung von Prochlorococcus ist enorm: Die Organismen produzieren schätzungsweise ein Fünftel des neu entstehenden Sauerstoffs in der #Erdatmosphäre, wie das Team um Francois Ribalet von der US-Universität Washington in Seattle erläutert. Sie besiedelten über 75 Prozent der sonnenbeschienenen Meeresoberflächen der Welt und machten in den nährstoffarmen tropischen und subtropischen Gewässern fast die Hälfte der #Phytoplanktonbiomasse aus. Damit sei #Prochlorococcus auch ein wichtiger #Startorganismus für die #Nahrungsketten der #Meere.

Thawing Out
Lake Erie, the shallowest of the Great Lakes, can almost completely freeze over in winter. In this satellite image of the lake in March 2025, about a third of the lake remains ice-covered, while sediment — resuspended by wind and currents — and phytoplankton swirl in the ice-free zone. In recent decades, scientists discovered that diatoms, one of the phytoplankton groups found in the lake, can live within and just below Erie’s ice, thanks to a symbiotic relationship with an ice-loving bacteria. This symbiosis allows the diatoms to attach to the underside of the ice and gather the light needed for photosynthesis. Even in the depths of winter, an ice-covered lake can teem with life.

Baltic Bloom
June and July brings blooming phytoplankton to the Baltic Sea, seen here in late July 2025. On-the-water measurements show that much of this bloom was cyanobacteria, an ancient type of organism among the first to process carbon dioxide into oxygen. These organisms thrive in nutrient- and nitrogen-rich waters. Here, they mark out the tides and currents that mix the Baltic. Zoom in on the full image, and you’ll see dark, nearly-straight lines across the swirls; these are the wakes of boats. (Image credit: M. Garrison; via NASA Earth Observatory)

We were warned! From September 2024. And now the #whales are falling silent!!! And #krill are dependent on whales as much as whales are dependent on krill!
#KrillHarvesting threatens #whale recovery
Soaring human demand for krill in the Southern Ocean poses a challenge to the recovery of whale species once hunted nearly to extinction. Stanford researchers identify the growing food conflict and offer solutions.
September 10th, 2024
"Human harvesting of krill in the Southern Ocean could threaten the recovery of whale species that were nearly wiped out by industrial whaling in the 20th century, according to a Sept. 10 study in Nature Communications.
"The tiny, shrimp-like crustaceans known as krill are the essential food source for baleen whales such as blues and #humpbacks. To feed, these giant marine mammals take in great gulps of ocean water, filtering krill through bristly mouth structures. Booming demand for krill as #FishMeal and #omega3 fatty acid nutritional #supplements, however, could leave whales without enough victuals to sustain even their diminished numbers.
" 'Our calculations suggest an alarming possibility that we might harvest krill to the point where we do real damage to recovering whale populations,' said lead study author Matthew Savoca, a research scientist in the lab of Jeremy Goldbogen, associate professor of oceans in the Stanford Doerr School of Sustainability.
"The results highlight a need for scientists, regulators, and industry to carefully assess the impacts of krill harvesting in the Southern Ocean at current levels before expanding. 'With this study, we want to draw attention to how there likely isn’t enough krill to support fully recovered whale populations, and now on top of that, we’re harvesting krill and plan to harvest more krill in the near future,' said Goldbogen, the study’s senior author
.
Counting on krill"The new research grew out of a prior Stanford study documenting how baleen whales gobble up significantly more krill than scientists had previously estimated. A paradoxical finding of that study was that, as whale populations plummeted by roughly 90% in the Southern Ocean during whaling’s grim heyday, so, too, did krill populations.
"The researchers worked out that #BaleenWhales effectively fertilize the ocean through their prodigious droppings, providing nutrients for the #phytoplankton that krill eat. The upshot: The krill population must have been much larger, perhaps five times greater, than it is currently to have sustained the pre-whaling whale populations in the early 20th century.
" 'Krill is the foundation of the entire Southern Ocean ecosystem. They’re really the only thing that large whales eat down there,' Savoca said.
"In the nearly 40 years since a global whaling moratorium went into place in 1986, some Southern Ocean species – particularly humpbacks – have made an impressive comeback. Yet this recovery has taken place against increasing competition with humans for the whales’ critical food source; over the past 30 years, the krill catch has quadrupled to around 400,000 tons annually and is set to expand further.
"Savoca and colleagues calculated how much krill is left in the Southern Ocean for baleen whales, seabirds, and other predators to eat after industrial krill harvesting at current rates, compared to the estimated amount of krill available before industrial whaling began. 'The basic math makes it pretty clear that the current krill biomass cannot support both an expanding krill fishery and the recovery of whale populations to pre-whaling size,' said Savoca."
