We got mentioned in the YSI Castaway (the manufacturers of the Conductivity Temperature Depth recorder that we use to measure salinity and temperature within our study area) Application Notes for 2011! Here is the quote;
"Recently, the CastAway-CTD was employed in a similar manner on BBC 1’s Ocean Giants, narrated by Stephen Fry. The first episode in a three-part series investigated why Blue Whales, usually a migratory species, stay around the Sri Lankan coastline in the warmer waters. Marine biologist Asha de Vos wanted to study the features of this water that sustain these whales year round, using the CastAway to record salinity and temperature levels at differing depths. She concluded, “Along our coastline, there are areas of mass upwelling of cold, nutrient rich water from the depths. These upwellings provide the perfect conditions for whale food; krill."
While CastAway retains all the advantages of a traditional CTD system, its additional appeal lies with its convenience, flexibility and speed—whether the instrument is being used in the freezing waters of the Arctic or the warm tropical waters of Sri Lanka."
