The most dramatic variations in pore water composition occurred in Holes 2 and 3 in the Gulf of Mexico. Both holes showed a strong increase in salinity with depth, evidently owing to diffusion from underlying salt bodies. However, on Challenger Knoll (Hole 2) a sharp drop in salinity was observed in the cap rock of the salt dome in which chloride fell to only 4.8 percent. The drop is attributed to

Virtually all iron objects recovered from a 7th century Byzantine shipwreck off the coast of Turkey were encrusted with a carbonate-rich layer. Mineralogical and chemical examination reveals limonite, siderite, and aragonite as dominant authigenic phases. The encrustations can be explained by oxidation (corrosion) of the metal in sea water. Analogous processes are suggested for many concretions fo

Disposable plastic syringes, fitted with screen discs and circles of filter paper, can be used to extract small amounts of pore water from unconsolidated sediments. A wooden screw frame or large C clamp supplies pressure for field use. Supplementary techniques enable small volumes of fluid to be recovered and handled easily. The Goldberg compensating refractometer provides a useful companion tool

In late June and July, 1967, the Deep Submergence Research Vehicle (DSRV) ALVIN, aboard its mother snip, LULU, proceeded from the spring base of operations, Nassau, to its home port of Woods Hole. During this trip, from July 2 to July 14, a series of five dives were made by ALVIN on the Blake Plateau off Georgia and South Carolina, and on the continental slope north of Cape Hatteras.

Published data on the elemental composition of the Ectoprocta (Bryozoa) are supplemented by new chemical analyses of 28 ectoproct samples, distributed among 13 species, for organic matter, CO2 calcium, magnesium, strontium, barium, phosphorus and iron. The new data, in addition to the 25 fairly complete analyses previously published (distributed among 19 other species) suggest the existence of 3 s

Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea (Fig. 1). This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which ultimately will end in November 1965, after the ship has circumnavigated the globe. The d

The listed publications represent a selection, by no means complete, of recent Soviet work in geological and chemical oceanography. Some works on hydrogeology and hydrochemistry of the continents, as well as a few publications on other subjects, such as geology, geophysics, and biology, also are included.
