| A standard, universally useful classification scheme for deepwater habitats needs to be established so that descriptions of these habitats can be accurately and efficiently applied among scientific disciplines. In recent years many marine benthic habitats in deep water have been described using geophysical and biological data. These descriptions can vary from one investigator to another, which makes it difficult to compare habitats and associated biological assemblages among geographic regions. Using geophysical data collected with a variety of remote sensor systems and in situ biological and geologic observations, we have constructed a classification scheme that can be used in describing marine benthic habitats in deep water. |

| In the present work, abundance, spatial distribution and qualitative composition, of benthic marine litter, were investigated in five study areas from the Eastern Mediterranean and Black Seas (Saronikos, Patras and Echinades Gulfs; Limassol Gulf; Constanta Bay). Surveys were performed using the monitoring protocol proposed by the Technical Group for Marine Litter. Densities ranged from 24 items/km(2) to 1211 items/km(2), with the Saronikos Gulf being the most affected area. Plastics were predominant in all study areas ranging from 45.2% to 95%. Metals and Glass/Ceramics reached maximum values of 21.9% and of 22.4%. The size distribution of litter items showed that >= 50% fall into medium size categories (10 x 10 cm, 20 x 20 cm) along with an elevated... |

| A new sand-dwelling dinoflagellate species, Cabra reticulata sp. nov., is described from sandy habitats in the south of Brittany (northwestern France). This new species possesses the characteristics of the 'unusual' genus, Cabra Murray et Patterson. The thecal plate formula is Po Pt 3' 1a 4'' 'x' 3c ?s 5''' 1'''' (or alternatively interpreted as Po Pt 4' 0a 4'' 'x' 3c ?s 5''' 1''''). Because of the strong lateral compression, cells of C. reticulata are frequently seen laterally and have a polygonal shape, with three prominent antapical pointed flanges and a dorsal spine in the anterior part of the hypotheca. The cingulum is ascending and incomplete. The thecal surface is ornamented with strong reticulations forming polygonal areolae, which differs from C.... |

| The carbon isotope composition (C-13) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the C-13 of foraminifera tests. Here more than 1700 C-13 observations of the benthic foraminifera genus Cibicides from late Holocene sediments (C-13(Cibnat)) are compiled and compared with newly updated estimates of the natural (preindustrial) water column C-13 of dissolved inorganic carbon (C-13(DICnat)) as part of the international Ocean Circulation and Carbon Cycling (OC3) project. Using selection criteria based on the spatial distance between samples, we find high correlation between C-13(Cibnat) and C-13(DICnat), confirming earlier work. Regression analyses indicate... |

| In coastal estuarine embayments, retention of water masses due to coastal topography may result in an increased contribution of continental organic matter in food webs. However, in megatidal embayments, the effect of topography can be counterbalanced by the process of tidal mixing. Large amounts of continental organic matter are exported each year by rivers to the oceans. The fate of terrestrial organic matter in food webs of coastal areas and on neighboring coastal benthic communities was therefore evaluated, at multi-trophic levels, from primary producers to primary consumers and predators. Two coastal areas of the French Atlantic coast, differing in the contributions from their watershed, tidal range and aperture degree, were compared using carbon and... |

| Twenty four species of ostracod have been found on Tarawa Atoll and fifteen on Kuria Island, Republic of Kiri-bati in the western Pacific Ocean. Thirteen species are common to both atolls. A consistent difference has been discovered in the ostracod faunas of Tarawa and Kuria, with those from Kuria showing coarser texture in the ornamentation than their counterparts from Tarawa. The variation of carapace ornamentation has led to multiple names for a species. A characteristic ornamentation at a particular locality may be a due to a small number of specimens colonising the new locality and having a limited gene pool. Alternatively, any variation in the ornamentation may be a clue to multiple phases of colonisation within a small area. |

| A new benthic phototrophic dinoflagellate is described from sediments of a tropical marine cove at Martinique Island and its micromorphology is studied by means of light and electron microscopy. The cell contains small golden-brown chloroplasts and the oval nucleus is posterior. It is laterally compressed, almost circular in shape when viewed laterally. It consists of a small epitheca tilted toward the right lateral side and a larger hypotheca. In the left view, the cingulum is more anterior and the epitheca is reduced. The cingulum is displaced and left-handed. This organism is peculiar in having no apical pore and its thecal plate arrangement is 2 ' 1a 7 '' 5c 3s 5 ''' 1 ''''. The plates are smooth with small groups of pores scattered on their surface.... |

| Guam consists of a single main island surrounded by shallow fringing coral reefs. The marine species and ecology of Guam's coral reefs have been studied extensively, especially through programs of the University of Guam's Marine Laboratory. In addition to overfishing and destructive fishing practices, the marine benthic communities of Guam have been damaged by major storm waves; loss of corals to crown of thorns starfish predation; damage by recreational swimmers, divers and watercraft operators; grounding of ships and pollutant discharges of sewage and of stormwater. But the most serious damage is due to accelerated siltation, sedimentation and turbidity due to erosion related to land use practices. Steps are being taken to protect Guam's coral reefs and... |

| Ecuador has a high diversity of ecosystems in its coastal and marine territory with beaches, bays, estuaries, cliffs, coastal lagoons and rocky coasts being the most representative. So far, 1,859 marine species have been identified in Ecuador. Of these, 1380 species of non-commercial marine invertebrates and vertebrates, belonging to 8 Phyla and distributed in 25 groups or classes, occur along the coast of Ecuador. These are: Protozoans, 9 groups: Oceanic and estuarine Diatoms, Cyanophyta, Chlorophyta, Dinoflagellates, Coccolithophorida, Silicoflagellates, Euglenophyta, Tintinnids and planktonic and benthic Foraminifera; Cnidaria, 2 classes: Hydromedusae and Scyphomedusae; Mollusca, 5 classes: Wood-boring molluscs and rock-boring and benthic bivalves;... |
