CRUISE NARRATION: |
8 October 1963 - 0830 departed Woods Hole. Partly cloudy and weather doubtful, but we headed south for continental slope stations near Atlantis Canyon. The big winch worked perfectly although one man watched it in the hold during the first few lowerings. Lost the 450' BT (#5388) due to a broken swivel. The first Station 1267 was a plankton tow only, taken on the way out. Station 1268, a routine sampling station, was taken at 2220. 9 October - The morning was windy but clear with a high pressure area coming in. Working conditions were marginal. Trouble with the bucket closing so we put in the weights. After lunch we resumed sampling with good results. About 2030 the seas became quite rough again and it seemed advisable to discontinue work. We reversed course and steamed off for the lee of Long Island and sampling was discontinued. Completed stations 1270-1273. Station 1274 was a plankton tow only because the sea was too rough to handle the bucket. 10 October - The day dawned bright and clear with calm seas. Steamed all morning to the first station south of Long Island and commenced working the standard 10-mile grid pattern with east-west lines. 1200 commenced Station 1275. Completed stations 1275-1282. 11 October 1963 - Gentle winds and blue sky. Smooth routine sampling all day. Completed stations 1283-1295. 12 October - Clear blue sky but NW winds made the water moderately rough. Routine sampling following the east-west grid pattern. Completed stations 1296-1305. 13 October - Seas calm with the ship rolling gently. We worked SW to Atlantic City then headed east toward Hudson Canyon. Completed stations 1305-1317. 14 October 1963 - Routine sampling across the shelf in the morning. With station 1326 at 1310 we changed to the van Veen sampler on the hydro wire and commenced doing deep stations down the slope. There was some trouble with the level wind on the hydro-winch but this was alleviated by taking the pin out of the mechanism while playing out the wire. The deep water stations were cut one short on the east end of the line because of naval maneuvers in the area. An attempt was made to sample the bottom of Hudson Canyon but it was unsuccessful. Completed stations 1318-1332. 15 October - Continued with the deep stations in gentle seas and light west wind. With station 1335 at 1325 changed back to the Campbell grab and commenced routine shelf stations. Headed in toward Cape May. Jogged down to the next line south to use up the time properly. Completed stations 1333-1341. 16 October - Moderate wind and sea. Made routine sample station toward Cape May. 1034 we broke off sampling and steamed into Cape May where we tied up at the Coast Guard base about 1400. 17 October - In Port - Cape May, New Jersey. 18 October - Depart Cape May at 1000 after fueling, encountered very dense fog at the harbor entrance which continued the rest of the day. We were unable to make the stations near shore because of the fog and so proceeded out on the grid pattern. Made the first station at 1520. Fog lifted in the evening and we continued with routine station sampling. Completed Stations 1348-1352. 19 October - Fine weather and clear skies in the morning. Routine sampling on lines east of Cape May. In late afternoon heavy fog closed in and curtailed the line being run toward the beach so we went 10 miles south and started back ease on the next line. Completed stations 1353-1365. 20 October - Continued sampling under good sea conditions. At 0555 we changed to the van Veen grab on the hydro wire at the first of the deep stations off the shelf edge. The first station made with the van Veen was unsuccessful, apparently the sample washed through on the first try leaving only a trace of unusable sample in the bucket. During the second attempt, weather reports of full gale warnings were received. The bucket was brought up and lashed. Because of the gale warnings we broke off work and departed on course 290 for Cape May. We tied up at the Coast Guard base at Cape May about 2000. 21 October thru 23 October - Tied up at Coast Guard base waiting for the seas from Hurricane Ginny to subside. Remained here thru 23 October. Most of the Scientists went to Washington, D.C. Heavy surf on the beach. 24 October - Depart Cape May 0900. Headed east to the shelf break to catch up on the deep water stations not done on the way to Cape May. Completed the first station but on the second station we could not obtain a sample in two tries. Suspect a rock bottom. Weather reports indicated the hurricane was again moving north so we abandoned the deep stations and headed north to complete the shelf stations before the hurricane forced us in again. 25 October - Near dead calm with an oily swell. Commenced shallow water station at 0600 and worked toward the Jersey coast then up the coast. Completed stations 1371-1355. 26 October - Gentle breezes and excellent sea conditions for working. Heavy fog forecast so we didn't get to New York Harbor entrance. Heavy fog in the morning but cleared toward mid-day. Routine shallow water sampling along Long Island, but in the dense fog it was not advisable to go into Long Island Sound because the radar was not operating properly. We therefore headed toward Woods Hole. Completed Stations 1336-1400. 27 October - About 0400 the fog lifted and we steamed down Vineyard Sound and docked at Woods Hole at 0920. |
