Description Chief Scientists: Paul Carlson, Guy Cochrane, Philip Hooge. Photo and Sidescan Sonar data (Kleinsidescan, 3dot5khz, underwatercamera, mudseis, imageprocessing) of field activity T-1-98-GB in Glacier Bay, Alaska from 08/21/1998 to 09/01/1998
Location Alaska
Summary 8/18-8/20--load and mob Tamnik 8/21-22 SSS lines 1-11 in Bug Bay, 12-27 in eastern Bug/Bartlett River area, 28-35 in Bug Bay proper. 8/22 2 camera drops in Bug Bay 8/22 3rd camera drop off NE side of Strawberry Is to look at grooves or striations (we need to look at these someday to see how similar they are to the Whidbey Passage ice gouges). 8/22 SSS lines in Fingers Bay (So and No) lines 36-92 (all lines to this point run at 100m range). 8/23-8/26 SSS lines 93-133 in Whidbey Passage. Changed range to 150m 8/27 SSS lines perimeter of Bartlet Cove (134-153) 8/27-8/28 grid over entrance moraine; lines 154-182 8/28 ran test lines around Bar Cove dock area; line Dock 75 & Dock 100 8/28 continued Bar Cove w/ lines across Bartlet River pro-delta area SSS lines 184-187 8/29 SSS lines 188-207 in area near Francis and Drake Is. 8/30 Camera drops 4-6 gully northeast of Drake. then SSS lines 208 & 212? 8/30 SSS lines 213-221?? in cove on ne side of Willoughby Is 8/30 SSS lines 222-224 in same general area--ie no of Willoughby??, then reran some Whidbey Passage lines (212 & 95) 8/31 Ran some of Philips famous tangential line along west shore of Whidbey Passage--lines 225-228 8/31--2 camera drops in gouge areas of W.P.until increased wind hampered work 8/31 reran line 167RR over south end of Bar Cove moraine 8/31 dock line 8/31, then redo of line 140=140RR Bar River mouth--ended line as passing dock and sewer outfall. 9/1 repack and demob 9/2 winch & other barge load to AK outpost? then beaucoup boxes to AK Air lv AK air to Juneau 6 pm
