The oceans are heating up, and marine ecosystems are changing because of it. Long before climate scientists realized the extent of impacts from carbon dioxide emissions, ocean scientists were taking simple temperature readings. Now those readings are off the charts, showing an ocean thrown out of balance from human-caused climate change. Sea surface temperatures hit a 150 year high off the U.S. East Coast from Maine to North Carolina during 2012.
These abnormally high temperatures are fundamentally altering marine ecosystems, from the abundance of plankton to the movement of fish and whales. Many marine species have specific time periods for spawning, migration, and birthing based on temperature signals and availability of prey. Kevin Friedland, a scientist in NOAA’s Northeast Fisheries Science Center’s Ecosystem Assessment Program, said “Changes in ocean temperatures and the timing and strength of spring and fall plankton blooms could affect the biological clocks of many marine species, which spawn at specific times of the year based on environmental cues like water temperature.”
