Abstract:
A multi-disciplinary and multi-institutional pilot expedition was organized by the National Centre for Antarctic and Ocean Research (NCAOR) to the ice-free areas of the Western Indian Ocean sector of the Southern Ocean onboard ORV Sagar Kanya during the austral summer of 2004 (January-March). This survey, conducted by the Central Marine Fisheries Research Institute (CMFRI), is the first Indian attempt to survey for cetacean diversity in the Southern Ocean. The ultimate objective is to determine distribution, relative abundance, migration patterns and critical habitat parameters. 68% of a total of 13 sightings (22 individuals) were positively identified and species observed included Antarctic minke whales (<i>Balaenoptera bonaerensis</i>), fin whales (<i>B. physalus</i>), sei whales (<i>B. borealis</i>) and blue whales (<i>B. musculus</i>). The blue whales were not identified to the sub-species level. The highest concentration of cetaceans was between 35° and 37°S (along 45°E) and between 48° and 53°S (along 45°E). Relatively small numbers of cetaceans were observed during the present cruise, possibly because most of the cetacean sighting effort was made during inclement sea conditions. Results on the sighting characteristics and occurrence patterns of the cetaceans in relation to the region and hydrographical parameters are discussed briefly <i>vis a vis</i> published information from the Southern Ocean.

Purpose:
To get a first hand information on the occurrence of cetaceans in the Southern Ocean as a part of first Indian attempt.

Benthos of Iranian parts of the Caspian Sea

Keywords: Observation, Iran, Occurrence, Benthos, Caspian Sea
Temporal coverage: 1968/2020

The Caspian Sea, which accounts for 40 to 44% of the total lacustrine waters of the world, is still suspected to be referred to as a sea or lake. Because of high biodiversity in the Caspian Sea and its coastal zone, it is one of the most valuable ecosystems on the earth. As this region has been isolated from other water bodies for a long term, high level of endemism is remarkably evident in its fauna. The existence of shallow areas, several deep depressions, and a wide range of salinities varying from 0.1‰ to 13‰ provide different ecological niches, giving rise to high species diversity.

Abstract:
A satellite tracking study was conducted on juvenile loggerhead sea turtles in the Indian Ocean. Eighteen individuals were fitted with transponders and tracked from Réunion Island (21.2°S, 55.3°E) in order to investigate movements and diving patterns. Nine turtles swam north towards Oman (20.5°N, 58.8°E), where one of the world’s largest rookeries of loggerheads is located. Three individuals travelled south towards South-Africa and Madagascar, countries that also host loggerhead nesting grounds. Fourteen of the transmitters relayed diving profiles. A dichotomy between diurnal and nocturnal diving behavior was observed. A greater number of shorter dives occurred during the day. Diving behavior also differed according to movement behavior as individuals spent more time in subsurface waters (&lt;10 m) during transit phases. The study provides an improved understanding of the oceanic movements and diving behavior of juvenile loggerheads. The results address a significant gap in the understanding of loggerhead oceanic movements and may help with the conservation of the species.

Purpose:
The purpose was to study the movement and diving behavior of late juvenile loggerheads in the western Indian Ocean.

Abstract:
The Gabon Sea Turtle Partnership has estimated that between 36,000 and 126,000 leatherback nests are laid on Gabon’s beaches every year, about 50% of which occur in Mayumba National Park, and about 23% in Pongara National Park (Witt et al. 2009).  This degree of reproductive effort suggests that Gabon hosts the largest nesting population of leatherback turtles in the world, and approximately 60% of all nesting females in the entire Atlantic Ocean.The objectives of this satellite tracking project are:(a)	Determine the number of nests laid per season per female and the duration between each nesting event.(b)	Assess the distance between successive nests during the season.(c)	Develop distribution maps of nesting and inter-nesting habitat use through high-resolution location data and diving behaviour data.(d)	Study the acoustic environment to which turtles are exposed at sea, through sound recording on the turtle.(e)	Evaluate the effectiveness of current protection measures and propose management regimes tailored toward addressing the overlap between sea turtle distribution and behaviours and anthropogenic activities.

The genus Volvarina (Gastropoda: Marginellidae) in Polynesia

Keywords: Observation, Occurrence
Temporal coverage: 2001/2002

Volvarina paumotensis (Pease, 1868), a Tuamotu Archipelago endemic species is studied with reference to its original description, and from living populations recently discovered on several atolls in the type locality. 
Two species of Volvarina discovered in Suwarrow, Northern Cook Islands, are studied. One of these is identified as being the previously described V. elliptica (Redfield, 1870), which has until now been considered as a species endemic to Fanning Island in the Line Islands (Kiribati). Additional records of shells from New Ireland and several Indonesian locations that have been provisionally identified by the authors as V. elliptica are given and it is cautiously suggested that the range of this species is extended to include these localities.
The animal and shell of the second species, V. nealei n. sp. are described and illustrated from a Suwarrow population discovered in an unusual micro-habitat associated with small brain corals in shallow water.

The Deepwater Program: Northern Gulf of Mexico Continental Slope Habitat and Benthic Ecology - DgoMB: Polychaetes

Keywords: Samplingevent
Temporal coverage: 2000/2002

A research program has been initiated by the Minerals Management Service (Contract No. 1435-01-99-CT-30991) to gain better knowledge of the benthic communities of the deep Gulf of Mexico entitled “The Deepwater Program: Northern Gulf of Mexico Continental Slope Habitat and Benthic Ecology.”
Increasing exploration and exploitation of fossil hydrocarbon resources in the deep-sea prompted the Minerals Management Service of the U.S. Department of the Interior to support an investigation of the structure and function of the assemblages of organisms that live in association with the sea floor in the deep-sea. The program, Deep Gulf of Mexico Benthos or DGoMB, is studying the northern Gulf of Mexico (GOM) continental slope from water depths of 300 meters on the upper continental slope out to greater than 3,000 meters water depth seaward of the base of the Sigsbee and Florida Escarpments. The study is focused on areas that are the most likely targets of future resource exploration and exploitation. However, to develop a Gulf-wide perspective of deep-sea communities, sampling in areas beyond those thought to be potential areas for exploration has been included in the study design. A major enhancement in the program is the extension of the transects onto the abyssal plain of the central Gulf of Mexico through collaborative studies with Mexican scientists. This additional work effort will allow assessment of benthic communities structure and function throughout the basin by sampling the deepest habitats in the region.
The program is designed to gain a better ability to predict variations in the structure and function of animal assemblages in relation to water depth, geographic location, time and overlying water mass. Biological studies are integrated with measurements of physical and chemical hydrographic parameters, sediment geochemical properties and geological characteristics that are known to influence benthic community distributions and dynamics. Eight (8) hypotheses are being tested on the basis of measures of benthic community structure. It is hypothesized that community structure varies as a function of: 1) water depth, 2) geographic location (east vs. west), 3) association with canyons, 4) association with mid-slope basins, 5) sea surface primary productivity, 6) proximity to hydrocarbon seeps, 7) time (seasonal and interannual scales), and 8) association with the base of escarpments.

Abstract:
Bahía San Antonio is home for bottlenose dolphins (whole year long) and southern right whales (winter months). Both species face a need of urgent increase in conservation management policies. On one side, the bottlenose dolphin population is declining in almost the entire country due to human induced factors as over fishing, pollution and habitat destruction. On the other side, the southern right whales are being under increasing pressure of tourism activities (whale-watching and swimming with whales) which are being executed without regulations. Our studies aim to gain information and knowledge on these species, to be able to implement urgent management strategies.

Purpose:
Boat-based observations are made in Bahía San Antonio, Patagonia, Argentina, in order to study residency patterns, abundance, and social composition of local bottlenose dolphins, and to study the behavioral response of southern right whales to human approaches.

Spatial distribution of epibenthic molluscs on a sandstone reef in the Northeast of Brazil

Keywords: Samplingevent
Temporal coverage: 2007/2007

The present study investigated the distribution and abundance of epibenthic molluscs and their feeding habits associated to substrate features (coverage and rugosity) in a sandstone reef system in the Northeast of Brazil. Rugosity, low coral cover and high coverage of zoanthids and fleshy alga were the variables that influenced a low richness and high abundance of a few molluscan species in the reef habitat. The most abundant species were generalist carnivores, probably associated to a lesser offer and variability of resources in this type of reef system, when compared to the coral reefs. The results found in this study could reflect a normal characteristic of the molluscan community distribution in sandstone reefs, with low coral cover, or could indicate a degradation state of this habitat if it is compared to coral reefs, once that the significantly high coverage of fleshy alga has been recognized as a negative indicator of reef ecosystems health.
