NOAA Releases SOCAT and GLODAP Data to Advance Ocean Carbon Monitoring - environment coastal & offshore
NOAA has released updated versions of the Surface Ocean CO₂ Atlas (SOCAT) and the Global Ocean Data Analysis Project (GLODAP) datasets, representing a significant advancement in ocean carbon monitoring. These peer-reviewed, integrated data ecosystems provide validated, real-time measurements crucial for understanding the ocean's role as a climate regulator. The releases bolster efforts to quantify the ocean carbon sink, as detailed in a related article from NOAA's National Centers for Environmental Information. These resources empower researchers and policymakers with empirical data to inform climate action strategies.
What is your favorite thing about oceanography/ what is it like to be an oceanographer?
Embarking on an oceanography degree is a significant commitment to understanding our planet's largest ecosystem. Oceanographers conduct vital, peer-reviewed research, employing integrated data ecosystems to monitor climate indicators and assess ocean health—a field increasingly critical given the urgency of ocean stewardship. Many find immense satisfaction in unraveling the complexities of marine systems, from nutrient pathways—as explored in our review of the Black Sea—to the profound impacts of deep-sea events. This career often involves fieldwork, though the extent of time spent at sea varies considerably.
Can someone help me identify this species? Devonport, Tasmania
Identifying marine life can be challenging, even for experienced observers. Our community is here to assist! A user in Devonport, Tasmania, recently sought identification for an organism found in the intertidal zone of Don Reserve – a possible sponge or algae. Sharing images is key to accurate assessment.
