Purpose
|
|
Seafloor mapping (using multibeam sonar and deep-towed
|
|
camera) and sampling (by dredge) of fossil and live cold-water
|
|
corals for paleo-oceanographic and ecological studies.
|
|
|
Information to be Derived
|
|
Samples and Chemical Analysis;Habitat maps;Bathymetric Maps;
|
|
|
Summary
|
|
Multibeam bathy was collected continuously. 6 TOWCAM
|
|
transects completed. 3 CTDs completed. 51 trawls and dredges
|
|
deployed and rocks, corals, and other animals photographed and
|
|
preserved. See bound cruise report for more information.

Notes

Navigation technique: gps;.

|
Seafloor mapping (using multibeam sonar and deep-towed camera) and samp
|
|
ling (by dredge and trawl) of fossil and live cold-water corals for paleo-oceano
|
|
graphic and ecological studies.
|
|
All multibeam and photographic data and fossil coral
|
|
specimens will be archived at WHOI. Modern coral specimens will be
|
|
archived at University of Hawaii. A separate scientific party from
|
|
the University of Texas shared the shiptime. They collected
|
|
multibeam bathymetry, underway magnetics and multichannel seismics
|
|
and dredged rock samples. Those data are not part of this project
|
|
and are archived at Univ. of Texas (P.I.s: Ian Dalziel and Larry
|
|
Lawver)
|
|
37 days at sea.
|
|
62 stations occupied.

Got Help?
|
For 08004, we would appreciate any information on -- analog materials, contract, days at sea, dive count, kms of navigation, national plan, NGDC Info, owner, project number, scanned materials, seismic description, station count, station description, submersible, tabulated info.
