Description

Excerpt from Seasonal Surface Currents Off the Coasts of Vancouver Island and Washington as Shown by Drift Bottle Experiments, 1964-65 Northwest Fisheries Center, Natl. Mar. Fish. Serv.. Noaa. Seattle, WA 98112. Seamount to Estevan Point, Vancouver Island, bc. Twelve corked, unballasted, short-necked (17 cm long with a 4i/2-cm base) drift bottles were released at 21 stations during each cruise. Ballast sand was not placed in the bottles to save handling time. These particular empty bottles already floated about 80% submerged and any improvement would be minor compared to other inherent errors in the method. Only minimum speeds are inferred by drift bottle data because there is no way of knowing how long the bottle was on the beach before recovery. Each contained a folded data card with instructions in English, Russian. And Japanese and four - digit serial numbers ranging from 6001 to 7044. A reward was offered for the return of each card. Recoveries from each cruise are discussed separately below. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
