Earth Day is April 22, a time to celebrate our incredible planet. It is also a time to recognize the serious challenges ahead, especially in the face of a changing climate. We know climate change is already impacting our ocean and coastal resources. This week, we are showcasing the ways NOAA Fisheries scientists are using the best available science to prepare for and respond to changing climate and ocean conditions.
Explore the features below to see how we are tracking and studying the impacts and providing best-in-class data and information for a Climate-Ready Nation.

Checking in with NOAA Fisheries Climate Scientists
“A Species like Goldilocks”: Discovering the Temperature Limits of Pacific Cod with Ben Laurel
Fish biology and where fish species live are heavily linked to water temperature. In his research at the Alaska Fisheries Science Center, NOAA scientist Ben Laurel focuses on how rising temperatures driven by climate change are impacting marine fish populations in Alaskan waters. When Ben isn’t in the field—catching Alaskan groundfish for scientific purposes—he researches young fish in the Alaska Fisheries Science Center’s unique cold water lab. The lab allows scientists to successfully study species from all regions of Alaska, including the Arctic. One of the main species he focuses on is Pacific cod. Pacific cod is the second largest commercial groundfish catch in Alaska, which makes understanding its future geographic distribution and abundance all the more important. But more than ever, the intensifying effects of climate change are hurting this fishery.
In this Q/A, Laurel explains how raising Pacific cod in a laboratory setting offers clues on how climate change is impacting this species.
“Dive Into the Issue”: Visualizing Climate Change With Melissa Karp
A new data visualization tool, the Distribution Mapping and Analysis Portal, or DisMAP, can help stakeholders like fishery managers and researchers understand and respond to changes in marine species' distributions. The portal uses NOAA Fisheries bottom trawl survey data—some dating back almost 50 years. Stakeholders can use the portal’s map-based visualizations to explore changes over time in the distributions of more than 800 different species of marine fish and invertebrates found throughout U.S. waters.
Explore how NOAA Fisheries’ new, interactive fisheries data portal shows how specific marine species’ locations have shifted over time, which may be in response to climate change. Check out this Q/A on the tool, featuring the portal’s project lead, Melissa Karp.
“Climate Change at the Water’s Edge”: Understanding the Impacts of Black Mangroves on Juvenile Shrimp
Climate change is transforming estuaries along the Gulf Coast. When they are young, these shrimp reside in estuarine habitats, like salt marsh, oyster reefs, and seagrass beds. They grow there before joining the adult shrimp population out at sea. However, the types of emergent vegetation in some estuarine habitats are starting to shift from salt marsh to black mangrove in many areas of the Gulf coast due to climate change.
The impacts of these changes to shrimp are yet to be understood. Read our Q/A with NOAA scientists Jennifer Doerr and Jennifer Leo, who are working to uncover how this may affect the shrimp fishery in the years to come.
“An Era of Surprises”: Studying Climate Change and Salmon With Nate Mantua
Growing up in a Northern Californian fishing town, Nate Mantua’s family owned a business connected to the local salmon fishing industry. When one of the worst El Niño events ever recorded hit the West Coast in 1982 and 1983, the salmon fishery his family relied on suffered. Nate would go on to study how to predict El Niño events in graduate school, years later. Now he works to understand the impacts of climate change.
In this Q/A, NOAA Fisheries scientist Nate Mantua discusses why he started studying salmon as well as how climate change and anchovies are threatening salmon on the West Coast. Nate leads a team of salmon ecologists, biologists, freshwater and ocean experts at NOAA Fisheries’ Southwest Fisheries Science Center. These scientists are examining how changing conditions in freshwater, estuary, and ocean habitats affect salmon on the West Coast, sometimes in unexpected ways.
“A Better Chance for Resilience”: Using Hungry Fish to Conserve Coral Reefs
Ocean warming and ocean acidification are big threats to corals. With rising temperatures, there are increasingly more ocean warming events that bleach corals. Corals unable to recover from bleaching eventually die, degrade, and disappear altogether. And, given the scale of ocean warming, one warming event can be linked to the eventual disappearance of a substantial amount of reef.
The ocean absorbs some of the excess carbon dioxide in the atmosphere. This has caused the acidity of the ocean to increase. As the water becomes more acidic, it reduces the amount of calcium carbonate available in the water that corals use to grow and repair their skeletons. As a result, it can be more difficult for corals to compete for reef space, and overall erosion of reef structure may increase.
NOAA scientist Tye Kindinger works at the Pacific Islands Fisheries Science Center, where she researches how reef fish help protect corals from the adverse effects of climate change. In this Q/A, Kindinger explains how identifying the best seaweed-grazing fish in the Pacific Islands region can help fight against seaweed overgrowth and promote recovery of distressed coral reefs.
