Deployment: OC449-02

2008-08-06 - 2008-09-04 Trans atlantic transect between Barbados and Cape Verde, 5-20 degN, 20-58 degW Platform:R/V Oceanus (vessel)

Description

R/V Oceanus Voyage #449, Leg II was a trans-Atlantic transect from Bridgetown, Barbados to Porto Grande, Cape Verde (5-20 degrees North, 20-58 degrees West). The main scientific objective was to test the hypothesis that the continental margin of northwest Africa provides a significant subsurface supply of iron to the open eastern tropical Atlantic.

Measurements include: CTD profiles, U/W Tow Fish Water Sampler, Trace Metal Profiles mostly in upper 1000 meters and one cast to 6000 meters, SeaSoar SeaMac Winch to deploy eleven battery-operated in-situ pumps with sci-provided non-metallic wire off the 01 deck using the side A-frame and SSSG non-metallic block and Gravity Coring
