The Derwent Estuary habitat project 1:25000 depicts marine habitats from Piersons Point [147 02, -43 03] to New Norfolk [147 02 , -42 42 ] from the coastline to the 40metre depth contour. The habitat types depicted in the dataset include reef, sand, seagrass, silt, silty sand and aquatic macrophytes. The data was collected through intensive field sampling from June to December 2000 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.

The River Derwent marine habitat project 1:12,500 depicts marine habitats from New Norfolk [147 03, -42 47] to Iron Pot [147 25, -43 03]. The habitat types depicted in the dataset include Cobble, Reef, Sand, Silt, Aquatic Macrophytes, Seagrass, and Vegetated. The data was collected through intensive field sampling from March to May 2007 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.

This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the University of Hawaii, BAE Systems Spectral Solutions and Analytical Laboratories of Hawaii, LLC. The goal of the work was to map the coral reef habitats of American Samoa, Guam and the Common Wealth of the Northern Mariana Islands by visual interpretation and manual delineation of IKONOS satellite imagery. A two tiered habitat classification system was tested and implemented in this work. It integrates geomorphologic reef structure and biological cover into a single scheme and subsets each into detail. It also includes thirteen zones. Benthic features were mapped that covered an area of 71.5 square kilometers of which 10.56 were unconsolidated sediment and 60.94 were coral reef and hard bottom. Of the coral reef and hard bottom class, 62.8% is colonized by greater than 10% coral cover.
