What caused a massive hole in Antarctic sea ice?
In 2016 and 2017, a massive hole developed in the Antarctic sea ice. Scientists investigated the processes that led to this formation and found that it was related to anomalous saltiness and storm activity in the region. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use […]
Phytoplankton Expanding Northward as Arctic Sea Ice Retreats
A recent study uses satellite data to show that Arctic sea ice retreat is causing changes in the timing and location of spring phytoplankton blooms, which play a large role in the regional ecosystem and carbon cycle. Channing PrendI’m a physical oceanography PhD student at Scripps Institution of Oceanography in La Jolla, California. I use […]
Millennial algae are not as productive: lazy, or less sea ice opportunities?
Why aren’t Arctic phytoplankton as productive as they used to be? Is it a lazy millennial thing, or something more complex and systematic? Researchers use observations to learn more about this generation of phytoplankton, and what it could mean for Gen Z and beyond… Nyla HusainI’m a 4th year PhD student at the University of […]
Sea Ice Modifies Biological Processes
A recent study investigates the relationship between sea ice variability and phytoplankton growth in climate models. Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean, therefore this work can help us understand and predict how the ocean’s ability to regulate climate might change in the future. Channing […]
When life gives you global warming, make pancake ice in ocean wave models
Sea ice is retreating, the Arctic is opening up, and wave activity is increasing. What does this mean for the ocean and atmosphere? The refreezing season of autumn may have some answers. Nyla HusainI’m a 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models to study small-scale turbulence […]
Sea Ice Drives Global Circulation
A recent study uses observational data from the Antarctic to show that sea ice processes help drive the global current system called the overturning circulation. This result suggests that changes to sea ice extent in the Antarctic could impact large-scale circulation as well as the ocean’s uptake of heat and carbon dioxide. Channing PrendI’m a […]
The Polar Vortex, Bomb Cyclones, and Climate
Bomb cyclones, the polar vortex, and climate – they’ve all been in the news in recent years, but how do they intersect? A new study finds a link between mid-latitude cyclones and enhanced sea ice melt in the Arctic. Nyla HusainI’m a 4th year PhD student at the University of Rhode Island Graduate School of […]
Why is Antarctic Sea Ice Growing?
Despite increases in global ocean temperatures, long-term trends actually show an increase in Antarctic sea ice extent. There are a number of reasons for this apparent paradox: geography, ocean properties, and atmospheric circulation to name a few. This paper examines the role of atmospheric variability in driving Southern Hemisphere sea ice trends. Channing PrendI’m a […]
Sea Ice Mixes it Up
Sea ice extent and concentration is driven by a complex combination of circulation and mixing, as well as interaction with the atmosphere. Understanding these processes is critical to improving climate models. This study uses models to examine the dynamics in marginal ice zones, which is becoming increasingly important for future climate predictions. Channing PrendI’m a […]
It’s getting cold in here!
As we here into winter, we notice changes taking place in nature all around us. But what do microbes in the ocean do when it gets cold??? Laura ZinkeI am a PhD student studying sediment geomicrobiology at the University of Southern California. My primary research interests lie deep under the sea studying how microorganisms survive […]
Melting ice, shifting microbes
Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]
Antarctic krill retreat to icy terrace homes for the winter
An international research time dives beneath the ice in Antarctica’s remote oceans to understand how krill larvae make use of sea ice to survive the winter and make it to adulthood. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and […]
Orca vs Narwhal
Orcas are natural predators of narwhals, but they are seasonally kept at bay by Arctic sea ice. As the Arctic becomes increasingly ice-free, killer whales are arriving earlier and hanging out longer in narwhal habitat. How do narwhals fare? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management […]
Atlantic confirmed as accomplice in Arctic sea ice loss
A team of scientist gathered new evidence from the Arctic Ocean, revealing a new suspect responsible for rapidly melting Arctic sea ice. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. For my research I sometimes […]
Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]
The Meltdown: Protists in the time of disappearing Sea Ice in the Arctic Ocean
Sea ice levels in the Arctic Ocean safeguard thousands of marine biosystems. Protists are little known micro-organisms that play a key role in maintaining a balanced oceanic ecosystem. Read more to see how climate change is affected sea ice-levels, and what that means for our protist comrades. Prabarna GangulyI’m a fourth year PhD candidate in […]
Sub sea ice technology aims to expand Arctic plankton surveys
A German research team tested out three devices for studying plankton in Arctic sea ice. These new methods might allow scientists to expand Arctic primary production studies and yield new insight into these important, understudied ecosystems. Eric OrensteinEric is a PhD student at the Scripps Institution of Oceanography. His research in the Jaffe Laboratory for […]
Pole wars: Episode 1 – The Phantom Sea Ice
In the sea ice battle between the North Pole and the South Pole, there is no winner in 2016, as sea ice cover is plummeting at both poles. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in […]
Positive real estate outlook for Antarctic krill
An Australian research team predict future sea-ice habitats for Antarctic krill larvae, and are surprised to find more suitable ice habitats in the future, despite shrinking sea-ice cover. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in […]
Why the Southern Ocean is getting less salty
The Southern Ocean has been getting less salty for decades, and scientists have finally proved that sea-ice is responsible for the extra fresh water in the ocean. Veronica TamsittI’m a PhD student at Scripps Institution of Oceanography in La Jolla California. My research is focused on the Southern Ocean circulation and it’s role in climate. […]
