Deep-water salps in Monterey Bay
Project Manager and Lead Scientist: Larry Madin
For 2005 work will continue on the new genus and species of salp, Vitreosalpa gemini (Tunicata: Thaliacea) that occurs at meso- and bathypelagic depths in Monterey Bay. The continuation involves additional approaches to measuring feeding and metabolism and extension of these observations and measurements to doliolids and appendicularians, the other important tunicates in the midwater environment. The objective is to obtain a more complete picture of the role of these grazers in the cycling of particulate material at midwater depths.
Development will also continue on laboratory methods to be adapted for use in situ on the ROV. The new methods will minimize handling of artifacts and obtain more realistic rates. Rate data obtained from lab and in situ measurements will be combined with data abundance and spatial/seasonal distributions of the different species from transect studies and data in the MBARI database and video archives. These methods will allow collection of essential information on the activity of these organisms and their role in midwater biogeochemistry.
