Today was the 41st trip taking monthly water samples as a part of a program run by the Institute of Marine and Antarctic Studies (IMAS), in Tasmania.
The study involves the collection of water samples at various depths up to 90 meters measuring temperature, salinity, dissolved oxygen, chlorophyll and turbidity.
Zooplanktin samples are also collected by using fine nets which are dragged through the water column. Additional samples are also taken for chlorophyll analysis and for phytoplankton.
The purpose of the study is to gather ecologically significant information and relate this information to samples collected 20 years ago. Differences can be used to identify changes that may be associated with climate change.
The day started out nice and calm with winds picking up to 20-25 knots by the end of the day. Skies were clear and there were multiple sightings of seals, dolphins and tuna particularly on the eastern side of Storm Bay.
