This is an OBIS formatted version of the Canadian government's Department of Fisheries and Oceans Maritimes Region database for visual sightings of cetaceans (e.g. whales, dolphins and porpoises) and other large pelagic animals (e.g. fish and turtles) mostly from the Scotian Shelf/Bay of Fundy portions of Canada's east coast. The collectors of these sightings are diverse (e.g. NGO researchers, fis

Updated distribution of sixteen species of seabirds along the Patagonian coast. Number of breeding pairs at colonies of penguins, cormorants, gulls and terns were evaluated by aerial, boat and ground surveys carried out between 1993-1995 during the implementation of the Patagonian Coastal Zone Management Plan (Fundaci?n Patagonia Natural and Wildlife conservation Society - GEF-UNDP).

The map shows the bottom types for Florida Bay that resulted from site surveys and boat transects (summer 1996-January 1997) compared with aerial photographs (December 1994-January 1995) and SPOT satellite imagery (1987). The purpose of this map is to describe the bottom types found within Florida Bay for use in 1) assessing bottom friction associated with sediment and benthic communities and 2) p

Research on coastal notothenioids of the South Shetland Islands area using trammel/gill nets and traps as sampling gear, operated from rubber boats. Distribution, feeding ecology and population dynamics of the most representative species. Monitoring of the impact of the offshore fishery on inshore fish populations in the South Shetland Islands area.

Settling velocities of the suspended sediment in the Kongsfjorden waters were obtained using owen tubes. Several measurements were achieved using different types of suspended sediment (Kogsfjorden waters, Bayelva plume, Goule Plume, Bayelva river, Goule river...), several concentrations and several air temperatures.

The observation programme will allow evaluating yearly the state of: - the pelagic ecosystem during the summer period from Dumont d’Urville to the shelf break and to the Mertz Glacier Tongue, - the seaice zone ecosystem in winter, - the benthic community observed by ROV in relation to icebergs and the dynamics of the Astrolabe glacier.

NASA Earthdata CMRcollection

Organic matter content from rocks and soils were achieved on the rocks in the watershed of the Bayleva, Goule and Kongsvegen rivers. Similar measurement were made on the bottom sediment in the Kongsfjorden. The aim is to determine the origin of the bottom sediment in the Kongsfjorden.

Second Palmer LTER field season at Palmer Station. Ocean water column observations were carried out twice a week from zodiacs over the Palmer near-shore grid. Bird observations were carried out on nearby islands.

NASA Earthdata CMRcollection

Database containing published information from scientific papers and reports of whales, dolphins and porpoises in the Atlantic Ocean, Magellanic region and South Pacific Ocean. Peripheral records from farther offshore include reported sightings in Malvinas/Falkland Islands, Drake Passage and the South Shetland islands. Distribution at near shore waters of open coast sheltered fjords, bays and rive

A brief bathymetric survey of the platforms around Favreau Pillar, Kirstensen Rocks and near Foyn and Possession Islands was made using a zodiac inflatable dinghy and a small portable echosounder. These were to collect data on the characteristics of nearshore submarine platforms, which appear to form an important part of coastal sediment transport paths. Observations through the crystal clear wate

The coastal characteristics of the Ross Sea shores was evaluated using the philosophy of the 'Oil Spill Persistence Index', established for low and temperate latitudes, to determine risk areas in the event of an oil spill in Antarctica. Observations were made to confirm the utility of distinguishing 4-5 major types of coast: a) bold, bare rocky coasts with generally high cliffs, b) beaches mostly

During the 1986-87 Expedition to Heard Island, a 3m inflatable boat was depoted at the shores of Winston Lagoon, on the islands' south-east coast. The boat was to allow access to the important Long Beach Elephant Seal harems for periods when flooding from the lagoon prevented passage across its spit. The availability of the boat together with a 'Furuno' echo sounder, a stabilised, floating, transd

Starting from the Spanish base Gabriel de Castilla, samples were collected at various locations within Port Foster from an inflatable boat. The collected samples were used to analyze variables, such as methane, pH, total alkalinity, dissolved oxygen, dissolved organic carbon, nutrients, chlorophyll and trace metals. Additionally, a multiparameter probe was deployed to obtain vertical profiles of p
