Náttúrulegt birkilendi á Íslandi er kortlagning yfir alla náttúrulega birkiskóga og birkikjarr á Íslandi. Helstu upplýsingar eru hæð, þekja og aldur. Skilið er á milli núverandi hæðar og aldur fullvaxta birkis. Það er gert samkvæmt alþjóðlegum skilgreiningum um hæð trjágróðurs þar sem miðað er við hæð fullvaxta skógar. Birki var fyrst kortlagt á árunum 1972-1975 og var unnin leiðrétting á gögnunum og gerðar frekari greiningar á árunum 1987-1991. Gögnin voru því komin nokkuð til ára sinna þegar ákveðið var að hefja endurkortlagningu á öllu náttúrulegu birki á Íslandi. Fór sú vinna fram á árunum 2010-2014 og er núverandi þekja því afrakstur þeirrar vinnu. Flatarmál náttúrulegs birkis á Íslandi er 150.600 ha. Frá árinu 1987 hefur flatarmál birkis með sjálfsáningu aukist um 9% og nemur 13.000 ha. Gögnin voru upphaflega hugsuð fyrir mælikvarða 1:15.000, hins vegar var talsvert stór hluti landsins kortlagður í mælikvarða 1:5000 – 1:10.000.

Survey transects is a line feature class containing transects completed in 2011.

A goal of the Government of Canada’s Coastal Environmental Baseline Program (CEBP) is to amalgamate historic environmental data from high vessel traffic areas. An extensive DFO biological sampling program was conducted from 1980 to 1981 on Sturgeon and Roberts banks located on the outer Fraser River estuary, BC, Canada. This report collates and simplifies three data sets: water quality and nearshore fish catch previously published as DFO Data Report 340 (Conlin et al.1982), and un- published weight-length (W-L) data for two locations on Sturgeon Bank (Iona and Steveston) and near Westshore Terminals (Coal Port) on Roberts Bank. W-L data were reconstructed from archived computer printouts using Optical Character Recognition methods. Analyses of water quality data indicate that the two banks provided different fish habitats with Sturgeon Bank having a greater freshwater influence. Although Iona area water quality was exposed to sewage outfall from a nearby sewage treatment plant, it appears that fish communities were not different from the other Sturgeon Bank area (Steveston). The fish communities were found to be different between the two banks with Roberts Bank having greater overall abundance and diversity. Interestingly, of the seven fish species used for condition factor analyses, five were found to have lower Relative Condition Factors in the Roberts Bank sampling area.

These data sets provide information pertaining to shrimp and bycatch estimates associated with beam-trawling and trapping (2001-2002) in Clio Channel. Data sets were compiled and formatted by Meagan Mak. Abstract from report: As part of a project investigating possible modification of marine ecosystems by shrimp trawling and trapping, we enumerated beam trawl and prawn trap catches at two locations in Clio Channel, south -central coast of British Columbia. Beam trawl surveys were conducted in Bones Bay and Turnour Bay during October 2001 and January 2002, respectively, and a prawn trap survey was conducted in Turnour Bay during March 2002. Catch data from the two gear types are presented.

Gagnasafn (GDB) NI_F25v_mikilvaegFuglasvaedi: Flákalag. Alls er 121 svæði á Íslandi sem telst alþjóðlega mikilvægt fyrir fugla. 70 svæði teljast til sjófuglabyggða (SF), 25 svæði eru fjörur eða grunnsævi (FG) og 31 svæði er votlendi eða önnur svæði inn til landsins (VOT). Nokkur svæði falla undir tvo eða þrjá flokka. Mikilvæg fuglasvæði er að finna í 65 af 74 sveitarfélögum landsins. Afar misjafnt er hversu mörg mikilvæg svæði eru skilgreind fyrir hverja fuglategund. Hjá varpfuglum eru langflest svæði skilgreind fyrir fýl (38) og hjá fargestum eru þau flest fyrir rauðbrysting (átta svæði). Fyrir 40 tegundir hafa engin mikilvæg svæði verið skilgreind. Alþjóðleg töluleg viðmið hafa ekki verið sett fyrir 21 þeirra en hinar 19 eru það fáliðaðar hér á landi að engin svæði teljast alþjóðlega mikilvæg fyrir þær. Kóðar fyrir fitjueigindir ‚Staða fitju‘ (stadaFitju) eru: 0 = ekki skilgreind áður sem mikilvæg fuglasvæði; 1 = skilgreind áður sem mikilvæg fuglasvæði, útlínur notað; 2 = skilgreind áður sem mikilvæg fuglasvæði, útlínum breytt; 3 = skilgreind áður sem mikilvæg fuglasvæði, útlínur NÍ; 4 = friðlýst, á náttúruminjaskrá eða votlendisskrá (getur auk þess verið skilgreind áður sem IBA), útlínur notað; 5 = friðlýst, á náttúruminjaskrá eða votlendisskrá (getur auk þess verið skilgreind áður sem IBA), útlínum breytt eða búið til; 6 = svæðið er hluti af öðru svæði sem er friðlýst, á náttúruminjaskrá eða votlendisskrá (getur auk þess verið skilgreind áður sem IBA) eða hluti þess er friðlýst, á náttúruminjaskrá eða votlendisskrá (getur auk þess verið skilgreind áður sem IBA), útlínur NÍ. [A total of 121 IBAs are defined. 70 IBAs are seabird colonies (SF), 25 IBAs are primarily intertidal zones and adjacent shallow marine waters (FG), 31 IBAs are inland, predominantly fertile wetlands and surface inland waters. A few IBAs fall under two or three categories. These IBAs lay in 65 of the 74 municipalities of Iceland. The number of IBAs designated for each species varies; by far, most breeding sites of Fulmarus glacialis (38). No areas were designated for 40 species. For more than half of those IBA-criteria have not been defined; others do not meet the criteria due to their small populations in Iceland. The feature attribute codes for ‘stadaFitju’ are: 0 = not previously designated as IBAs; 1 = previously designated as IBAs, outline unchanged; 2 = previously designated as IBAs, outline changed; 3 = previously designated as IBAs, outline drawn by IINH; 4 = protected or on the Register of areas of conservation interest (could as well be previously designates as IBAs), outline unchanged; 5 = protected or on the Register of areas of conservation interest (could as well be previously designated as IBAs), outline changed; 6 = .area is part of an area that is protected or on the Register of areas of conservation interest (could as well be previously designated as IBAs) or part of this area is protected or on the Register of areas of conservation interest (could as well be previously designated as IBAs), outline drawn by IINH.]

PURPOSE: The objective of the program is to gather environmental coastal data to better understand fluctuations in water temperature and its effect on coastal marine species. DESCRIPTION: Bottom and surface water temperatures are monitored in coastal waters of the southern Gulf of St. Lawrence using electronic recording devices attached to navigational buoys or moorings and set to record every two hours. PARAMETERS COLLECTED: temperature (environmental); point (spatial) NOTES ON QUALITY CONTROL: Data are checked for irregularities. SAMPLING METHODS: Temperature recording devices are installed by fishermen, DFO staff and, since 2000, by the Canadian Coast Guard staff. USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

Zooplankton samples were collected at Ocean Station "P" (50.0000, -145.0000) from 1956 to 1980, and were analyzed to various levels of taxonomic resolution over the years. Although summaries of these data have been previously published ((LeBrasseur 1965) and (Fulton 1978, 1983)) the detailed species data have never been published. This detailed dataset contains total zooplankton wet weights/m3 for the whole period of 1956 to 1980, as well as densities (numbers/m3) for five major taxa (copepods, chaetognaths, euphausiids, amphipods, and Aglantha) from 1964 to 1967, species identifications, counts and lengths for many samples collected between 1968 to 1980. The attached supporting document (Ocean Station "Papa" detailed zooplankton data: 1956 – 1980) contains information on the methods used to collect and process the data along with descriptions of a number of fairly minor points about the data that were not resolved. It also describes, in detail, the format of the original data files, the corrections/changes that were made to these files in creating this version, and how these errors affect what was published in Fulton (1983). The purpose of this record is to make the detailed data available to the scientific community in an electronic format and to provide a convenient reference for citing the detailed data.

The Steller sea lion (Eumetopias jubatus) is the largest of all sea lions and enjoys a lifespan of up to thirty years. In Canada, the Steller can be spotted along the rocky coast of British Columbia. These highly mobile marine mammals typically travel alone or in small groups, but they congregate in large numbers at traditional rookeries and haul-outs during the mating and pupping season. The population was severely depleted in Canada but following its protection in 1970, the size of the adult population has more than doubled. The survey targeted Steller sea lions and sites were chosen based on knowledge of historically occupied rookeries and haul-out sites with nearby areas monitored for potential shifts in distribution. This dataset contains counts that have been collected from sightings of individuals in the 2016/2017 survey season.

This dataset contains observations of species occurrences from seafloor imagery collected by the remotely operated underwater vehicle (ROV) during the 2012 Expedition to Cobb Seamount. The ROV operated by Fisheries and Oceans Canada was a customized Deep Ocean Engineering Phantom HD2+2 which collected photographic images from 12 transects ranging from 35 m to 211 m in depth.
