AEROCE Acronym for Atmosphere/Ocean Chemistry Experiment, a multi–disciplinary and –institutional program focusing on a number of aspects of the atmospheric chemistry over the North Atlantic Ocean. The objectives of AEROCE are:
• to gauge the impact of anthropogenic sources on the chemical and physical properties of the atmosphere;
• to assess the consequences of the perturbuations on natural processes including climate; and
• to predict the longer term efforts via the use of models.
The program officially started in 1987 with coordinate measurements from four stations, i.e. Barbados, West Indies; Bermuda; Izan˜a, Tenerife, Canary Islands; and Mace Head Ireland. Five more stations were added in June 1995 to give greater geographical coverage of continuous measurements of bulk aerosol chemical composition and condensation nuclei.

AESOP Acronym for Alaska Environmental Satellite Oceanography Project, a collection of remote sensing experiments and projects being performed at the Institute of Marine Sciences at the University of Alaska Fairbanks. This seems to have been mothballed as of 2001. This is part of the larger SEA Project.

AESOP Acronym for Antarctic Environment and Southern Ocean Process Study, also known as the U.S. Southern Ocean Joint Global Ocean Flux Study (JGOFS). AESOP involved studies of two different and distinct regions. The first was the Ross Sea continental shelf, where a series of six cruises (on the R.V.I.B. Nathaniel B. Palmer) collected data from October 1996 through February 1998. The second was the southwest Pacific sector of the Southern Ocean spanning the Antarctic Circumpolar Current (ACC) at 170◦W, where data were collected during five cruises (on the R.V. Roger Revelle) from September 1996 through March 1998, as well as during selected transits between New Zealand and the Ross Sea.
The objectives of the project were to:
• better constrain the fluxes of carbon in the Southern Ocean,
• identify the factors and processes regulating the magnitude and variability of primary productivity, and
• gain a sufficient understanding of the Southern Ocean to model past and present carbon fluxes with sufficient accuracy to predict its response to future global changes.
The findings of AESOPS include:

• the Ross Sea continental shelf is among the most productive of all Antarctic systems, with a significant seasonal cycle;
• a seasonal bloom occurs in the region of the Polar Front;
• the annual production of the Ross Sea can be quantified by measuring deficits of nutrients and dissolved carbon dioxide;
• the phytoplankton blooms in the Ross Sea have essentially no losses due to microzooplankton herbivores;
• while iron did not stimulate phytoplankton growth in low silica waters north of the silica gradient, it substantially stimulated diatom growth in waters south of the gradient;
• the Polar Front region exhibits extreme mesoscale variability; and
• dissolved organic carbon concentrations increase seasonally by less than a third as much as particulate organic carbon levels.
