The Ecology and Biogeography of Heard Island Marine Benthos 1987/88

Keywords: Occurrence
Temporal coverage: 1988/1988

Collections of 23 macroinvertebrate taxa associated with Durvillaea antarctica holdfasts and 58 invertebrate taxa associated with artificial substrata collectors are described from shallow-water and intertidal habitats at Heard Island. The fauna sampled possessed strong biogeographic affinities with the Kerguelen Island fauna and, to a slightly lesser extent, the fauna recorded at Macquarie Island. The fauna possessed negligible affinity with the Antarctic. Experiments involving the offshore tethering of Durvillaea antarctica holdfasts indicated epifaunal invertebrates rapidly abandoned detached holdfasts, but that the few species surviving after one day can probably survive long periods adrift. 

The fields in this dataset are:

Taxon (species)
Distribution
Locality
Date
Control
Quality: A preliminary trial indicated that whole plants attached to lines created too much drag for anchors, hence holdfasts were separated from fronds and tethered at the sea surface to anchored buoys. This process was undertaken on 20 November 1987, with four of the tethered holdfasts collected for faunal analysis the next day. Two holdfasts were lost to wave action during the study, with the remaining two holdfasts collected after 93 days afloat. Holdfasts (4 replicates) were also collected as faunal controls from the shore at the start (20 November 1987) and end of the experiment (21 February 1988).

In order to assess whether recruitment was occurring on tethered holdfasts, four replicate holdfasts were defaunated by submersion in freshwater for 10 minutes at the start of the experiment before offshore tethering (see Edgar 1992). Two of these recruitment control holdfasts were lost through wave action and two collected at the end of the experiment. On collection, all holdfasts were carefully placed into plastic bags and formalin added. Animals were later separated from holdfasts in the laboratory by pouring the washed contents of the bags through a 0.5 mm sieve after the holdfast had been broken apart, and animals retained by the sieve counted under a binocular microscope using the same methods as for artificial algal habitats.

DFO Pacific Shorekeepers Intertidal Survey – a community based project

Keywords: Observation, Occurrence
Temporal coverage: null/null

The Shorekeepers survey is a citizen science protocol based project that enables community groups to collect scientifically defensible information about the intertidal and sub-tidal habitats and their biota in British Columbia. 
 
Shorekeepers is a rigorous monitoring methodology. The key to getting reliable scientific data is to use standard survey methods so that everyone is collecting data in the same way over time at all sites. A monitoring guide developed by Fisheries and Oceans Canada presents an intertidal surveying methodology. The method is presented in a logical step-by-step manner starting from selecting a study area through each type of measurement to entering the field data into the database, and finally, reporting the results. After a few days of training in habitat mapping and species identification, community members can use these step-by-step protocols to routinely monitor their site of interest or concern. The challenge is to distinguish natural changes from human-induced ones over time. Nevertheless, the resulting data will help us all to gain a better understanding of these dynamic ecosystems, and to make wiser decisions about coastal development and marine conservation.

To detect gradual changes to habitats and local biodiversity, we need long-term data sets. Shorekeepers is about collecting detailed data annually at the same site(s) for three or more years.

As our population grows in coastal areas, so may our impacts on marine habitats. Protection of this fragile environment requires active participation and monitoring by local people and communities. Does there appear to be less marine life on a particular beach in recent years? Do you suspect that a nearby activity or industry is affecting the plants and animals of a particular shoreline?

Shorekeepers is stewardship of coastal marine habitats by people who live near them. It is a monitoring methodology designed specifically for community groups and for people who may not have a strong science background to be able to contribute to scientific data collection. Having local community groups and individuals take an active role in looking after their coastline fosters "local ownership" and interest.

DFO maintains the central database with the complete dataset from all shorekeeper surveys on the BC coast. The OBIS dataset is a subset of this larger collection and includes the date, location and percentage coverage of the intertidal area by various taxa.  Quantitative abundance and biomass values are not included in this dataset.  Information on the tidal cycle and the slope of the intertidal area is included in the notes.

The OBIS dataset is a subset of the Shorekeepers collection and contains presence information for intertidal zone taxa.  For the full dataset users should contact DFO.
BOEM Beaufort Sea, Alaska, Fish and Invertebrate Haul and Catch, with Oceanography, 2008 

Keywords: Observation, Occurrence
Temporal coverage: 2008/2008

The Minerals Management Service (MMS), Alaska OCS Region funded a pilot survey in 2008 of the offshore marine fishes of the Beaufort Sea. This was the first offshore marine fish survey to have taken place since an opportunistic survey in 1977 (Frost and Lowry 1983). The overarching goal of the survey presented here is to generate a baseline against which to assess the effects of offshore development on marine fish and to provide information for designing mitigation measures.
This pilot survey provided recommendations for future monitoring methods in addition to baseline data against which to compare future anthropogenic and climate impacts. Demersal fish and benthic invertebrates were assessed using standardized bottom trawl gear and methods. Pelagic fish abundance was assessed using hydroacoustics and midwater net tows. The distribution of zooplankton was sampled with small-meshed bongo nets and physical oceanographic data were collected with conductivity-temperature-depth instruments.

Abstract:
Boat-based acoustic and visual surveys for harbor porpoises (<i>Phocoena phocoena</i>) were conducted during the summers of 2001 and 2002in order to investigate their distribution and relative abundance in the Baltic Sea, and to compare the results with the adjacent Kiel and Mecklenburg Bights and the Little Belt.

Purpose:
Harbor porpoises are subject to year-round bycatch in gillnets and other fishing gear in these waters. This is of particular concern in the Baltic Sea where a survey carried out in 1995 indicated that the population is low and current levels of anthropogenic mortality are believed to be unsustainable.

Dataset credits:
Kevin Foss, Christopher Newport University; 
U.S. Department of the Navy

Abstract:
The Elizabeth River is bounded almost totally by industrial, urban, suburban, commercial shipping and military facilities. Tidal in nature, the river has low flow, resulting in heavy contamination loads. The population studied is the Northern Migratory Stock of the US Atlantic coast, appearing in this area from May through November. Standard small boat, focal group follow, passive observation techniques were used, along with photography of individuals. Data on location, group size estimates, activities observed and relevant environmental observations were recorded every five minutes. The dolphins appear as individuals or pairs in April and May, with group size increasing in June to a peak mean of 29 animals sighted per encounter. Group size then decreases in October and November. Probability of encountering dolphins ranges from 0% during the winter and early spring to over 80% in July, tapering off towards fall. Activity patterns show greatest diversity in July and August, with travel constituting the main activity early and late. Despite a peak of births in the area in May-June, there is little mating until July, with the incidence of sexual activity peaking in September.

Purpose:
To better understand the seasonality and behavior of bottlenose dolphins in the lower Chesapeake Bay.

Data were originally collected by Mr. Kevin Foss at Christopher Newport University during field seasons from 2000-2006. Data were subsequently acquired by the U.S. Navy in 2013.

Supplemental information:
[2015-03-24] A few records had a wrong animal count of zero. The value is replaced with a blank representing species presence only.

These data are the result of small boat transects with focal group follows, so that sightings were recorded at regular intervals. Therefore, there may be sightings of the same individuals at different times.

Records that originally estimated a range for the number of adults were attributed with the median number to be conservative.

Three records on land were excluded.
