Field Activity 1979-029-FA

Identifier 1979-029-FA
Alternate names 79-7
Purpose Investigate change in shelf sediments and morphology caused by hurricane runoff by a major river.
Location inner shelf near Rio de la Plata, Dorado, Puerto Rico, United States, North America, North Atlantic;
Summary Successful job. Sediment samples: 33; Echo sounder profiles: 15 km; SCUBA dives: 12.
Info derived Grain size analysis; Sea floor map; Bathymetric maps;
Comments Very successful and exciting. However, we had extreme difficulty getting enough people together to get to sea. SCUBA diving takes 3 people in the boat (two must go down and one must stay in the boat as a matter of safety). At the same time, a minimum of two people is needed for navigation control ashore, and not all people are capable of that work. Five good people is minimum, and we were hard put to find a fifth capable of the work, as is suggested by the list of participants. This lost us some good scientific data because it delayed our work until quite a few days after the event, the results of which we were investigating.
