What are SIP files?

Files that are delivered with Sea-Bird Scientific and third party equipment to describe the sensors data output and calibration coefficients come in two types. Calibration files or *.cal files and telemetry definition format files or *.tdf files. In some cases, systems are created that network many sensors together and their combined data is provided in one serial output. The simplest example is a HOCR sensor that generates both light and dark frames. A more complex example is a HPROII profiling system that may contain as many as 5 sensors and 7 individual calibration and tdf files. These files must be used to both collect and process the data. This can become quite confusing to keep track of all these files so Sea-Bird Scientific developed SIP files. All CAL and TDF files required for a system are zipped using winzip and the extension changed from *.ZIP to *.SIP. The file name includes the system description (usually the network master serial number) and the creation date. This SIP file can then be used in place of individual files to collect and process data.

Bioshutter II

The Bioshutter II is an autonomous underwater shutter attachment designed for use with Satlantic radiometers. The primary purpose of the shutter is to prevent marine bio-fouling of the sensor optics in moored, time-series application. Copper, and copper-based alloys have long been known to have good resistance against bio fouling and have been used in a diverse variety of commercial applications. Scientists working at the University of California Santa Barbara Ocean Physics Lab under the auspices of the National Ocean Partnership Programs' (NOPP) Ocean System of Chemical, Optical, and Physical Experiments (O-SCOPE) project developed an underwater shutter device for use with instruments such as Satlantic's OCR-500 and HyperOCR series instruments. The Satlantic Bioshutter II device builds upon the success of this instrument by combining an innovative copper shutter and an input power controlled motor drive assembly to ensure robust operation in harsh marine environments.
