Full description

This record describes an aggregated data product compiled from a number of different surveys of Macrocystis surface cover in Tasmanian waters, spanning 1950 to 2019.

Some surveys represent a statewide census of Macrocystis cover, while others are targeted surveys of smaller regions. Methodology and data quality may also vary between surveys. Please see linked metadata records for specific methodologies and quality statements applying to individual surveys.

Lineage

Statement: Surveys of the surface (areal) extent of Macrocystis were conducted on multiple occasions using a range of methodologies (visual survey by boat, digitising of aerial photographs from light aircraft etc). Surveys were conducted in 1950-53, 1965, 1970-71, 1986, 1988, 1999, 2009 and 2019. Polygon data from all surveys was combined into a single data product (no spatial operations conducted). Note that attributes collected varies between surveys. Quality and spatial resolution generally improve with more recent surveys, but please see linked metadata records for specific methodologies and quality statements applying to individual surveys.
