Research Confirms Link Between Snow Crab Decline and Marine Heatwave – NOAA Fisheries
“During the marine heatwave, snow crabs faced a triple threat,” said lead author and Alaska Fisheries Science Center stock assessment scientist Cody Szuwalski. “Their metabolism increased, so they needed more food; their habitat was reduced so there was less area to forage; and crabs caught in our survey weighed less than usual. These conditions likely set them up for the dramatic decline we saw in 2021…”
Seaweed is mucking up beaches. This robot could stop it — and fight climate change – NPR
In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…
