A preliminary report on the manganese nodule field southwest of Western Australia published in this Journal recently (Frakes, Exon and Granath, 1977) quoted chemical analyses...

Oxide coatings on sediments, especially iron, are ubiquitous in the oxygenated environments of most lakes. Deposits of ferromanganese oxides are especially abundant in many...

Dark crusts and concretions on volcanic and calcareous rocks dredged from seamounts west of the Aeolian Islands, southern Tyrrhenian Sea, consists mainly of amorphous Fe-Mn...

In the green Oligocene clay of Krizanovice (former Krzyzanowicz) the author found numerous black nodules. In the 3-4 centimeter thick black crust of a particular specimen the...

During Discovery Cruise 11, April-May 1966, eleven hauls were made on the crest and on the southern facing slope of Palmer Ridge in the Peake Deep area in order to fill out the...

One of geological peculiarities in the Julian Alps is red pelagic limestone containing manganese nodules. They are encountered at several localities in the Bovec, Trenta and Krn...

A detailed geophysical and geological survey of the Mariana Trough, an actively extensional back-arc basin, was conducted in 1976 and 1977 to provide data for selection of...

A German coring device (Reineck, 1958) has been improved to obtain oriented, undisturbed cores at any depth of water. The samples are rectangular in shape, 8 × 12 inches in plan...

Manganese nodules collected off Baja California have layers (zones) which are texturally and compositionally distinct. Massive and mottled zones consist mostly of...

61 manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections at the University of Hawaii,...

Eighteen stations were occupied; 13 dredge hauls were collected on seamount, atoll, and island flanks and three box cores were taken from the sediment cap of an unnamed seamount...

Adam Mickiewicz University staff has studied the area since 1984, using the old hut Skottehytta as a base until 2009. In 2011, a temporary station was built nearby. It was moved...

The accretion rate of manganese nodules and the sedimentation rate of the underlying sediment has been studied with 10Be and 14C on a nodule covered hill in the Madeira Abyssal...

Stable carbon and oxygen isotope ratios in single plant components in Sphagnum peat have a good potential to reveal environmental changes in peat archives. Two peat profiles,...

Upper Quaternary marine sediments recovered from the West Antarctic continental margin are characterized by a distinct lithological succession allowing the reconstruction of...

Based on field investigations in northern Russia and interpretation of offshore seismic data, we have made a preliminary reconstruction of the maximum ice-sheet extent in the...

The sediment temperature distribution at mud volcanoes provides insights into their activity and into the occurrence of gas hydrates. If ambient pressure and temperature...

Atmospheric _p_CO~2~ is a critical component of the global carbon system and is considered to be the major control of Earth's past, present and future climate. Accurate and...

This study subdivides the Potter Cove, King George Island, Antarctica, into seafloor regions using multivariate statistical methods. These regions are categories used for...

This dataset is a compilation of 1,207 lake basal ages used to identify spatial and temporal patterns of lake formation across the high northern latitudes. Data was gathered...
