(Table 1) Interstitial water chemistry at DSDP Leg 81 Holes
Interstitial water studies on samples obtained during Leg 81 have revealed substantial changes with depth in dissolved calcium, magnesium, strontium, potassium, and lithium.... -
(Table 1) Chemisity of interstitial water at DSDP Leg 66 holes
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... -
(Table 1) Sulfur content and sulfur-isotope ratios at DSDP Leg 82 Holes basalts
The sulfur contents of 21 basalt samples from four DSDP Leg 82 holes were determined and the isotopic compositions of sulfur were measured on 15 of them. Most of the basalts are... -
(Table 1) Stable carbon isotopic composition of CH4 and CO2 of DSDP Leg 84 Holes
Interstitial gases were collected from Holes 565, 566, 567A, 568, 569A, and 570 drilled during Deep Sea Drilling Project Leg 84 on the Glomar Challenger. The samples were... -
(Table 1) Interstitial water chemistry at DSDP Leg 78A Holes
Studies of interstitial water carried out during Deep Sea Drilling Project Leg 78A (Sites 541, 542, and 543) have revealed that alteration of volcanic material dispersed in the... -
(Table 1) Interstitial water chemistry at DSDP Leg 80 Holes
Interstitial water studies of sediments recovered during DSDP Leg 80 (Goban Spur transect) indicate a well-developed dissolved-sulfate minimum at Site 548 resulting from... -
(Table 1) Concentrations and carbon isotopic compositions of CH4 and CO2 at D...
The principal gaseous carbon-containing components identified in the first 400 m of sediment at Deep Sea Drilling Project Site 533, Leg 76, are methane (CH4) and carbon dioxide... -
(Table 1) Interstitial water chemistry at DSDP Leg 76 Holes
Low salinities and strong opposing fluctuations between chlorinity and interstitial water d18O and dD characterize the region of gas-hydrate occurrence at Site 533. In addition... -
(Table 1) Interstitial water chemistry at DSDP Leg 73 Holes
Interstitial waters obtained from a transect east from the Mid-Atlantic Ridge on progressively older oceanic crust (Sites 519-522) indicate a general absence of concentration... -

(Table 1) Organic geochemistry at DSDP Leg 71 Holes
Forty-three core samples from Sites 511 through 514 of DSDP Leg 71 were analyzed geochemically. The black shales at the bottom of Hole 511, in the basin province of the Falkland... -
(Table 1) Interstitial water chemistry at DSDP Leg 72 Holes
Interstitial waters collected at Sites 515 and 516 during DSDP Leg 72 have been analyzed for major and minor constituents. At both sites increases in dissolved calcium and... -
