The Argo Program: Two Decades of Ocean Observations

In a recent article published in Frontiers in Marine Science, the history of the Argo program is examined and discussed. The Argo program began in 1998 when a team of international scientists, known as the “Argo Science Team,” proposed the idea for a global array of autonomous floats to obtain temperature and salinity measurements of the upper 2,000 meters of the global ocean. The new array of floats, called Argo, would go on to be endorsed as a pilot program of the Global Ocean Observing System and be used to fill in the large data gaps in ocean observations.

New Data Set to Improve Tropical Atlantic Ocean and Atmospheric Research

Researchers at NOAA AOML have released a new tropical Atlantic data set that includes several enhancements to improve data accuracy and data collection in the tropical Atlantic. The new data set is called enhanced PIRATA, or ePIRATA, and provides continuous records of upper-ocean temperature, salinity, and currents, together with meteorological data such as winds, humidity, and solar radiation. ePIRATA should prove valuable in better analyzing ocean and atmospheric processes in the tropical Atlantic.

PIRATA, the Prediction and Research Moored Array in the Tropical Atlantic, is a multinational observation network, established to improve knowledge and understanding of ocean-atmosphere variability in the tropical Atlantic. It is a joint project of Brazil, France and the United States of America, motivated by fundamental scientific issues and by societal needs for improved prediction of climate variability and its impact on the countries surrounding the tropical Atlantic basin. PIRATA provides measurements at 18 locations throughout the tropical Atlantic

AOML Oceanographers Collect Coast to Coast Measurements on the GO-SHIP Indian Ocean Cruise

During the months of March and April, AOML joined an international team of oceanographers to actively sample the Indian Ocean in support of the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP), an initiative to measure and investigate the ocean basins from coast to coast and from top to bottom. Aboard the R/V Roger Revelle, the team transected the Indian Ocean from the Antarctic northward into the Bay of Bengal, collecting seawater samples at 113 stations as part of a multi-decadal effort to measure various ocean properties, including temperature, salinity, nutrients, carbon and other gases.
