Ship-of-opportunity hydrographic data from R/V Gyre Cruise 93G-03: Galveston, Texas, to Colon, Panama. Technical rept. (Final)

Leg One: Galveston, TX, to Cozumel, Mexico (9-15 March). Cruise 93G-03 departed Galveston at 19:45 CTS on 9 March for a Training and Research cruise with objectives to (1) sample surface nutrients and chlorophyll within the low salinity outflow from Galveston Bay on to the inner Texas shelf; (2) deploy XBT's along a Topex groundtrack in the central Gulf, in cooperation with remote sensing specialists at the US Naval Research Laboratory at Stennis Space Center, MS, and with the LATEX.Eddy program; (3) collect zooplankton for study of diel migration patterns of siphonophores and other groups within the upper 100 m; and (4) deploy a benthic lander to measure metabolism of carbonate sands on the Campeche Shelf at Arrecife Alacran. Leg Two: Cozumel, Mexico, to Colon, Panama (15-20 March). From Cozumel, Gyre proceeded to Puerto Castilla, Honduras, where scientists from Honduran universities boarded the vessel for a cooperative program of sampling off the Honduran coast. Six CTD casts, as well as plankton and benthic sampling, were made during a general survey of the Mesquitia shelf region. The CTD and nutrient data from those Honduran stations are included in this report, although the plankton and benthic data will be reported separately
