Numerically predicted changes in the circulation of the Gulf of Mexico accompanying a simulated hurricane passage

To obtain a quasi-steady-state basic circulation pattern for the Gulf of Mexico, a barotropic prognostic numerical model, with no changes in input conditions and with sufficient friction, has been used. It has been found that a simulated hurricane that would theoretically pass across the Gulf of Mexico from the Yucatan Strait to a point just east of the Mississippi Delta would generate a two-centered cyclonic flow region in the western Gulf waters, with a remnant of the steady-state anticyclonic flow in the northwestern corner...

Recent dissolved-oxygen measurements in the Gulf of Mexico deep waters

In 1963 it was suggested that rather large gradients in dissolved oxygen exist in the Gulf of Mexico below a sill depth of between 1500 m and 1900 m. However, measurements made on three cruises during 1966 and 1967 indicate that there is no clearly discernable horizontal variation in dissolved oxygen in these waters...
