Condition of rocky reef communities around Tasmania: algal surveys, Australia (1992-1995 and 2006-2007)

OBIS Australia Open in mapper Explore occurrences

The data is the percent algal cover derived from underwater visual census methods involving transect counts at rocky reef sites around Tasmania. This data forms part of a larger dataset that also surveyed fish and megafaunal invertebrate abundance for the area. The aggregated dataset allows examination of changes in Tasmanian shallow reef floral and faunal communities over a decadal scale - initial surveys were conducted in 1992-1995, and again at the same sites in 2006-2007. The originating metadata record http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=75fc95bf-e4b4-4d39-9ac3-0433669648de contains project details, additional contacts and on-line resources.
