Tascam

TASCAM is currently off-line due to a radio communication issue.

Repairs have been scheduled and it will be back on-line soon.

Thanks for your patience


Watch this Space!

An updated version of the TASCAM buoy site is coming soon……..

TASCAM is used to remotely collect physical and biological data on the water quality of Tasman Bay recording long-term data on simple, but significant parameters, like temperature, salinity, turbidity (sediment) and chlorophyll – all indicators of the quality and productivity of our coastal waters.

Cawthron's latest coastal monitoring platform is the first buoy in New Zealand waters to utilise inductive instrument technology and has been developed in collaboration with the California-based Monterey Bay Aquarium Research Institute (MBARI).

TASCAM's aim is to meet the needs of multiple stakeholders, providing information on the local marine environment not only to researchers and local councils but also day-to-day end users like industry (e.g. mussel farmers) and even recreational fishers.

Located in western Tasman Bay, TASCAM has been situated to build on the wealth of knowledge gained during the multi-year Integrated Catchment Management Programme but has been largely funded by Cawthron in the hopes to see the TASCAM, and others like it form part of a nationwide network providing standardised data sets to provide a national picture of what is happening within New Zealand waters.

Data are downloaded on an hourly basis at the top of the hour and plots are generated automatically and uploaded to the site at fifteen to twenty minutes past the hour. Therefore most up-to-date data is available for viewing about twenty minutes past each hour.

Notes on how to interpret the plots:

Wind and current Rose Plots: Wind and current rose plots are, by definition, offset by 180 degrees to one-another. In other words, the wind rose plot shows the frequency, speed and direction that the wind is coming from whereas a similar current rose plot would show the direction the currents are flowing towards.

Vector Stick-plots: These plots are a sequential time series of the current speed and direction with each 'stick' representing a single value as a vector of magnitude and direction (North = straight up). There is a very good explanation of how to read these plots at: http://gyre.umeoce.maine.edu/gomoos/stick.html
