A core of foraminiferal-coccolithic oozes filling a valley of the transform fault located at 29°40'S on the South Atlantic Ridge contains layers composed of angular fragments of...

The radiocarbon method was used to measure primary production of Zooxanthellae of five colonial radiolaria and two pelagic foraminifera from the tropical Atlantic Ocean; in...

Concentrations of sulfate ions at three depths in the water column of the Black Sea were studied during cruises of the GOIN (State Oceanographic Institute) Sevastopol' Division...

Two samples of pumice, obtained by trawling from depths of 3100 and 4300 m on the eastern slope of the Great Meteor Seamount in the Atlantic Ocean, have been examined. Their...

Ultrafiltration with tagged atoms was used to study physicochemical states (dissolved, colloidal, suspended) of Mn, Co, Ni, Zn, and Ce in bottom and interstitial waters...

Results of radiocarbon dating of 23 cores (81 determinations) collected in the Red Sea rift zone at 8°N are presented. All of the main tectonic structures were dated: the upper...

Barite ores with admixture of sphalerite that occur in the Atlantis-II Deep are indicated by their geological position, structure, and mineral and chemical characteristics and...

It is found that hydrocarbons are constantly accumulated on the main geochemical barriers: water-atmosphere, river-sea, water-suspended matter, and water-bottom sediment...

Results of four year (1977-1980) observations on concentrations of organochlorine pesticides in waters of the North Atlantic (between 10°N and 60°N) are presented. Gas-liquid...

Comparison of daily and diel variability of chlorophyll-a concentration at three long-term stations in meso- and eutrophic regions indicates that their values are similar. Daily...

Multiplication rate and production of zooflagellates were determined in the Central Indian Ocean. In the surface zone of the areas studied zooflagellate generation time ranged...

Two lithological-stratigraphic intervals have been distinguished in the Morocco basin by a study of lithologic composition of bottom sediments as well as of planktic and bottom...

Results of radiocarbon dating of bottom sediments from the Baltic Sea are presented for four areas investigated during Cruises 16 and 26A of R/V Akademik Kurchatov. The dating...

A study of chemical and isotopic composition of coastal thermal springs and waters of the Kraternaya Bay, Yankicha Island, revealed that the total mineralization and...

Total mercury concentration in waters of the Atlantic Ocean and Mediterranean Sea measured in January-April 1982 varied from 0.007 to 0.192 µg/l. Particulate form was 1.6-16% of...

Particles sinking out of the euphotic zone are important vehicles of carbon export from the surface ocean. Most of the particles produce heavier aggregates by coagulating with...
