Deep Ocean Argo Floats, New Approach Yield New Insights into Ocean Acidification

Thanks to the National Oceanic & Atmospheric Administration and a joint US-Canadian research team, it is now possible for marine scientists to use satellite data from five-foot-tall Argo floats that drift with deep ocean currents to remotely monitor ocean acidity (pH) and the total carbon dioxide (CO2) content of seawater to better understand changes in ocean chemistry.

50 Million Year Old Fossil Clams Shed Light on El Nino and Global Warming

One current climate theory suggests that global warming could result in El Nino conditions becoming permanent as opposed to occurring in prevailing two- to seven-year cycles. New research based on a study of a long-lived species of fossilized clam that lived of the coast of Antarctica indicates that was not the case during the early Eocene, when the Earth was as warm as it's been in the last 65 million years.

Warming Atlantic Waters Lure Mackerel North and East

Atlantic mackerel are moving north and east, dispersing more widely into warmer waters off the US and Canadian continental shelves, according to new research from NOAA fisheries scientists. The findings are of significance to commercial and recreational fishermen, and indicate broader changes within the regional marine food web are likely underway.

New Climate “Normals” Begin on July 1st – Warmer is the New Norm : NOAA Releases 2010 State of the Climate Report

New weather normal baseline data is adopted on July 1st

Tomorrow the National Oceanic and Atmospheric Administration (NOAA) will incorporate new baseline data reflecting new climate “normals” for 1981-2010. For the past decade baseline normals spanned the period from 1971-2000. These normals “serve as a 30 year baseline average of important climate variables that are used to understand average climate conditions at any location and serve as a consistent point of reference,” said the …
