Samples of Temperature and Salinity from a CTD profile have been measured at Station 9 in the Derwent Estuary between August 2012 and January 2013.

Samples of Temperature and Salinity from a CTD profile have been measured at 6 Stations in the Derwent Estuary between August 2012 and January 2013.

Samples of Temperature and Salinity from a CTD profile have been measured at Station 3 in the Derwent Estuary between August 2012 and January 2013.

Samples of Temperature and Salinity from a CTD profile have been measured at Station 2 in the Derwent Estuary between August 2012 and January 2013.

Samples of Temperature and Salinity from a CTD profile have been measured at Station1 in the Derwent Estuary between August 2012 and January 2013.

Underwater video technology was used to observe marine mammal interactions (seals, in particular Australian fur seals) within midwater trawl nets. A camera system was placed inside the trawl net in the vicinity of a Seal Excluder Device, designed to prevent megafauna from entering the codend of the net and provide an escape point. Digital video data was described according to a range of operational, catch and interaction fields, and made time-specific to each trawl shot. Data is linked to commercial catch and effort data providing operational, environmental and catch information.

Samples of Temperature and Salinity from a CTD profile have been measured at Station 6 in the Derwent Estuary between August 2012 and January 2013.

Describes the database used for storing Southern Rock Lobster (Jasus edwardsii) biological data collected by observers on commercial boats and dedicated research trips incorporating information on sex, length, weight, damage, reproduction, bycatch, protected species interaction, location, depth, tagging and equipment type.
