The Application of In Situ Video Technology to Plankton Ecology
The collection of marine zooplankton using plankton nets is a 200 year old technology. This kind of conventional sampling results in samples that reflect the integration of those plankton living over relatively large spatial scales, from meters to km's in size. In addition many of the important zooplankton living in the sea contain no hard parts and are gelatinous (e.g. jellyfish, tunicates (slub}, etc.), resulting in their destruction during net collection. Thus, we have no idea of the abundance and location of these small organisms on the scale on which they actually live, which is mms to a meter or so, and we have even less idea of the distribution and abundance of delicate, gelatinous zooplankton. Over the past 10 years there have been some innovative new approaches to sampling zooplankton in the sea. Among the most promising of these approaches is the deployment of magnifying video cameras in the sea, from ship or on moorings. We have been collecting both types of video record for several years from the Arctic and from Newfoundland waters, particularly from our moored observatory in Bonne Bay. This video plankton recorder information will allow revolutionary new knowledge of the organismal-scale distribution and abundance of zooplankton in the sea, including the aggregation of zooplankton at the thermocline and pycnocline, and the small scale feeding and reproductive behaviour of zooplankton.
