(eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office) 84 https://doi.org/10.2973/dsdp.proc.84.app.1985 961-967 During Leg 66, a transect was drilled across the Middle America Trench off Mexico. In this report, interstitial water analyses for Sites 487 (on oceanic crust), 490, 491, and 492 (continental slope apron), and 493 (upper continental slope) are presented. All sites are characterized by high sedimentation rates, and as a result sulfate reduction and methane generation processes are very important. At Sites 490 through 492 decreases in chlorinity are evidence of the presence of gas hydrates. At Site 493 a sharp increase in dissolved calcium and the complete depletion of dissolved magnesium just above basement indicate that weathering of continental crust is still an ongoing process. -99.1753 -98.9255 15.8535 16.381 -98.9894 16.180514285714285 1979-03-24T00:00:00 1979-04-24T00:00:00 3.0 620.0 DSDP Deep Sea Drilling Project https://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 66-487 15.8535 -99.1753 North Pacific/TRENCH -4764.0 1979-03-24T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 190.5 m 119.6 m 20 cores; 180.5 m cored; 9.5 m drilled; 66.3 % recovery 66-490 16.1593 -99.0565 North Pacific/TRANSITION ZONE -1761.0 1979-04-08T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 588.5 m 343.4 m 63 cores; 577 m cored; 9 m drilled; 59.5 % recovery 66-491 16.029 -98.9722 North Pacific/SLOPE -2883.0 1979-04-13T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 542 m 389.4 m 58 cores; 532.5 m cored; 4.5 m drilled; 73.1 % recovery 66-492 16.0788 -98.9453 North Pacific/SLOPE -1935.0 1979-04-20T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 279 m 177.5 m 29 cores; 260.2 m cored; 0 m drilled; 68.2 % recovery 66-493 16.381 -98.9255 North Pacific Ocean -645.0 1979-04-24T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 670.5 m 330.8 m 56 cores; 518.5 m cored; 28.5 m drilled; 63.8 % recovery 66-493A 16.381 -98.9255 North Pacific Ocean -645.0 1979-04-24T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 12 m 7.6 m 2 cores; 12 m cored; 0 m drilled; 63.3 % recovery 66-493B 16.381 -98.9255 North Pacific Ocean -645.0 1979-04-24T00:00:00 Leg66 Leg66 1979-03-18T00:00:00 1979-03-18 1979-05-02T00:00:00 1979-05-02 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Watkins, Joel S Watkins, Joel S Moore, John C Moore, John C doi:10.2973/dsdp.proc.66.1982 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 126 m 59.4 m 12 cores; 114 m cored; 0 m drilled; 52.1 % recovery 532 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ DEPTH, sediment [m] is given in mbsf.
