600-year-old marine sponge holds centuries old climate records By Diana Udel
Temperature records show past volcanic activity, current climate warming trends
MIAMI Scientists used a 600-year-old marine sponge to reconstruct a record of ocean temperature in the North Atlantic revealing past volcanic activity as well as the current global warming trend from the release of carbon dioxide and other heat trapping gasses into Earth’s atmosphere and absorbed by the oceans.
The University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led research team used geochemical proxies to reconstruct a 600 year-long record of Atlantic Ocean temperatures from the skeleton of a sclerosponge (

MIAMI A new collaborative study lead by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and the National Oceanic and Atmospheric Administration (NOAA) found evidence of growing numbers of critically endangered smalltooth sawfish within coastal waters off Miami, Florida, an area where the regular presence of this rare species had gone largely undocumented, until now. The new findings are part of a NOAA initiative to support and enhance the recovery of smalltooth sawfish in and around Biscayne Bay, a coastal lagoon off Miami, that was designated a Habitat Focus Area by NOAA in 2015.
