Community Structure of Macrobiota and Environmental Parameters in Shallow Water Hydrothermal Vents off Kueishan Island, Taiwan.
Hydrothermal vents represent a unique habitat in the marine ecosystem characterized with high water temperature and toxic acidic chemistry. Vents are distributed at depths ranging from a few meters to several thousand meters. The biological communities of shallow-water vents have, however, been insufficiently studied in most biogeographic areas. We attempted to characterize the macrofauna and m...

متن کاملSulfur and oxygen isotope insights into sulfur cycling in shallow-sea hydrothermal vents, Milos, Greece
Shallow-sea (5 m depth) hydrothermal venting off Milos Island provides an ideal opportunity to target transitions between igneous abiogenic sulfide inputs and biogenic sulfide production during microbial sulfate reduction. Seafloor vent features include large (>1 m(2)) white patches containing hydrothermal minerals (elemental sulfur and orange/yellow patches of arsenic-sulfides) and cells of su...
متن کاملShallow-Water Hydrography in Portugal Using ERS-SAR Data
Introduction The aim of hydrography is basically to chart the underwater topography. A precise knowledge of the sea-bottom features has great relevance mainly in shallow waters, where navigational safety must be assured at any cost. Ideally, one should have available a complete series of maps of the sea-bottom topography. approximately 100 km x 100 km. Although the basic information provided by...
متن کاملAre hydrothermal vents oases for parasitic protists?
mosquitoes is well known. As Hoffman and Miller comment, ‘We suggest a combination of directed wind and volatile repellent might be developed as a mosquito deterrent strategy for the backyard setting’ [3]. Indeed, the combination of DEET and permethrin in a coconut base (Mosbar) as a malaria control measure looks promising (M. Rowlands et al., unpublished). Volatile oils from plants can serve a...
