Abstract |
This dataset
consists of polygons representing areas of Southern Right Whale activity
other than migration within the study area for the proposed Recherche Archipelago
marine protected area, off the southern coast of Western Australia. Attributes
include description of activity, period of activity, source of attribution,
and source of polygon. Southern Right Whale activity polygons are identified
at a broad scale only and are suitable for regional representation.
The dataset has been developed as part of CALM Marine Conservation Branch's resource assessment of the region. The resource assessment has been undertaken to assist in the marine reserve implementation process for the proposed Recherche Archipelago marine protected area. This dataset is complemented by a line dataset - Southern Right Whale migration paths in the Recherche Archipelago. It is also complemented by other fauna datasets within the region including furseal breeding and haul-out islands, sealion breeding and haul-out islands, and seabird breeding islands. The dataset was generated from anecdotal information provided by experts, and from published information [Bannister (1994)] gathered during a literature review of marine wildlife in the region. Southern Right Whale activity polygons were then compiled on base maps by Kevin Bancroft and the dataset was digitised and attributed by Ben Lamb in February 2002. This is the first stage in the generation of this dataset. The dataset will be upgraded as priorities, time and resources permit. |

Lineage |
1.
Hardcopy base maps containing a coastline, broadscale bathymetry information
(10m, 20m, 50m, 100m, 200m isobaths), Australian maritime boundaries and
the proposed study area were generated. Maps were produced at a scale of
approximately 1:350 000.
2. Bernie Haberley (ex CALM wildlife officer), Klaus Teiderman (CALM staff) and Fud Mckenzie (Sealion Charters) were consulted to delineate Southern Right Whale areas of activity on the hard copy base maps based on their knowledge of marine wildlife in the region. See attribute SOURCE_A for details. Bannister (1994) was also refererred to as an aid in identifying areas of activity. 3. Polygons were digitised on screen using the hard copy base map as a reference. Digitising was undertaken at scales of between 1:50,000 and 1:250,000. Polygons were cut to the DOLA coastline 28/02/2001 where the two intersected. 4. Polygons were attributed as per the base map and other sources (see attribute SOURCE_A), and data was checked for logical consistency. Where polygons overlapped the area of overlap was attributed with the multiple sources. 5. Data datum transformed from AGD84 to GDA94 using the change datum functionality of the extension 'CALM Added Functionality v2000' in Arcview3.2. 6. The dataset was checked against CALM MCB Marine Information System standards and metadata reviewed by Mark Sheridan. |

Positional Accuracy |
The data
has been collated from information provided by experts and a literature
review during a rapid assesment of the marine fauna usage of the area.
Resource and time constraints prevented more detailed survey work being
undertaken. Due to the nature of the study, positional accuracy should
be considered as approximate only as these polygons represent a general
area in which the activity takes place. Delineation of areas of activity
may not be comprehensive.
Positional inaccuracies may also have occurred due
to;
Digitising of polygons from the hard copy base maps varies in positional accuracy from 50m to approximately 250m (based on accuracy of 1mm at digitising scale). |
||||||
Attribute Accuracy |
The data has
been collected from anecdotal information provided by knowledgeable people
who are familiar with the area and regularly observe marine wildlife use
of the area. A literature review was also undertaken to leverage previous
work that has been done in the area. Detailed survey work has not been
undertaken. Delineation of areas of activity may not be comprehensive.
Due to the resource and time constraints of the project,
not all relevant attributes have been given values. These include relationship
to any physical features eg isobath.
|
||||||
Logical Consistency |
Attribute names
have been checked and validated for consistency across all wildlife datasets
created for the implementation of the proposed Recherche Archipeligo marine
protected area.
Attribute values have been checked and validated for consistency, and checked for logic in relation to attribute names. The shapefile has been compiled carefully to avoid overlaps or duplication of points. |
||||||
Completeness |
The dataset
is complete as at the date of this metadata statement. The dataset will
be upgraded as priorities, time and resources permit.
Further work needs to be undertaken on delineation and ground-truthing of many areas of wildlife distribution/activity. Feedback that would contribute to the quality of this dataset is appreciated. |
