Particles were collected from the dilute portion of neutrally buoyant hydrothermal plumes from four Mid-Atlantic Ridge sites (MARK, 23°N; TAG, 26°N; Broken Spur, 29°N; Lucky Strike, 37°N). Comparison of data from proximal portions of the TAG (Atl

Dissolved concentrations of CH 4 , H 2 and Mn have been measured in a hydrothermal plume above the shallow water ( c. 250m) Steinaholl vent site at 63°N on the Reykjanes Ridge. Samples were taken in October 1990 and June 1993. In 1990 dissolved CH 4

Hydrothermal sediments from the NESCA vent-field, Escanaba Trough, are enriched in a number of typical “vent-fluid” metals for which fluid data for the same, sediment-hosted, site exhibit anomalous depletion. These results are consistent with coo

We have completed a systematic survey for hydrothermal activity along the Reykjanes Ridge from 57°45′N to 63°09′N. Shipboard determinations of total dissolvable Mn (TDMn) and dissolved Si, CH4 and H2 have revealed evidence for only one site of
