Powerful new tools for working with Argo data

June 9, 2022

No single program has been as transformative for ocean science over the past two decades as Argo: the fleet of robotic instruments that collect measurements of temperature and salinity in the upper 2 km of the ocean around the globe. The Argo program has been instrumental in revealing changes to ocean heat content, global sea […]

What can algae tell us about translating laboratory science to nature?

June 9, 2022

Ocean acidification research has grown over the past few decades. Much of recent research documents negative impacts of changing carbonate chemistry on calcifying marine organisms in laboratory experiments. At the 2018 Ocean Acidification PI Meeting, a group of us asked “Can these laboratory responses to ocean acidification be scaled up to accurately predict the responses […]

What drives decadal changes in the Chesapeake Bay carbonate system?

May 3, 2022

Understanding decadal changes in the coastal carbonate system (CO2-system) is essential for predicting how the health of these waters is affected by anthropogenic drivers, such as changing atmospheric conditions and terrestrial inputs. However, studies that quantify the relative impacts of these drivers are lacking. A recent study in Journal of Geophysical Research: Oceans identified the […]

Unmixing deep sea sedimentary records identifies sensitivity of marine calcifying zooplankton to abrupt warming and ocean acidification in the past

May 3, 2022

Ocean acidification and rising temperatures have led to concerns about how calcifying organisms foundational to marine ecosystems, will be affected in the near future. We often look to analogous abrupt climate change events in Earth’s geologic past to inform our predictions of these future communities. The Paleocene-Eocene thermal maximum (PETM) is an apt analog for […]

How do coccolithophores survive the darkness?

April 1, 2022

Coccolithophores have survived several major extinction events over geologic time. The most significant was the asteroid impact at the K/T boundary, followed by months of darkness. Additionally, coccolithophores regularly reside in the twilight zone, just beyond the reach of sunlight. A paper recently published in the New Phytologist addresses how these photosynthetic algae can persist […]

Predators Set Range for the Ocean’s Most Abundant Phytoplankton

April 1, 2022

Prochlorococcus is the world’s smallest phytoplankton (microscopic plant-like organisms) and the most numerous, with more than ten septillion individuals. This tiny plankton lives ubiquitously in warm, blue, tropical waters but is conspicuously absent in more polar regions. The prevailing theory was the cold: Prochlorococcus doesn’t grow at low temperatures. In a recent paper, the authors argue ecological […]

Decline in spring chlorophyll-a concentrations in response to COVID-19 lockdown in the Yellow Sea

February 18, 2022

Recently, it was reported that the coronavirus (COVID-19) pandemic-related lockdowns have led to a reduction in anthropogenic emissions of pollutant nitrogen on a global scale. This reduction may have induced a change in marine environmental conditions, providing a natural experiment for determining its impact on marine ecosystems. However, a direct cause-effect relationship between COVID-19 and […]

New Data Standard for Oceanographic Research

February 18, 2022

Effective data management is paramount in oceanographic research. The ocean is a global system, and research to understand regional and global oceanographic processes often involves compiling cruise-based data from different laboratories and expeditions. The new international data standard covers column header abbreviations, quality control flags, missing value indicators, and standardized calculation of numerous parameters. Released […]

Seagrass is not a silver bullet for climate change

January 21, 2022

Coastal management actions aimed at protecting or restoring seagrass meadows are often assumed to have the collateral benefit of removing large amounts of carbon dioxide from the atmosphere to combat climate change. Be aware, however: not all seagrass meadows are alike. Under certain conditions, some release more carbon dioxide than they absorb and are net carbon sources to the atmosphere. This is now shown […]

Aircraft reveal a surprisingly strong Southern Ocean carbon sink

December 17, 2021

The Southern Ocean is indeed a significant carbon sink—absorbing a large amount of the excess carbon dioxide emitted into the atmosphere by human activities—according to a newly published study led by the National Center for Atmospheric Research (NCAR). The findings provide clarity about the role the icy waters surrounding Antarctica play in buffering the impact […]
