Bornö Workshop 2015

Watermass Transformation


The Bornö Workshop 2015 was focused on watermass transformation. Presentations of current research was given during the day, followed up with discussion on past, present and future challenges.

In mornings, breaks and afternoons, CTD (conductivity, temperature, depth) and ADCP (accoustic doppler current profiler) measurements were made off the bridge (see results below). Unfortunately, equipment damage put an early end to measurements.

In the afternoons, there were presentations about the participants' current research.

Place and Time

Monday, July 27 to Friday, July 31 at Bornö Stationen, a small retreat in Sweden (see on map).
