The annual report summarizes the field efforts of the previous sampling year, provide graphical and tabular summaries of collected data and place these data within historical context so that unusual observations can be identified. The sampling year ends after the October cruise, so the final certified data will not be available until after the instrument returns from the Sea-Bird calibration facility, typically in November or early December. The December oceanographic cruise will take place in December or January; the Annual Data Report will normally be generated in January or February. Because water column samples of phytoplankton, suspended sediment, and dissolved oxygen are not taken and analyzed, the ancillary data sensors cannot be quantitatively compared on an inter-cruise or inter-annual basis, nor even within the same cruise (it is acceptable to compare measurements within the same cast, however). For example, different phytoplankton species have different responses as measured by the fluorometers. Consequently, even within a single cruise, data are not directly comparable because phytoplankton communities within a fjord near a glacier may well have different species compositions from communities more closely connected to the Gulf of Alaska. Similarly, field personnel have no way to calibrate the OBS sensor in situ to particle size distribution, shape, color, reflectivity, etc., so turbidity measurements among casts and cruises must be interpreted with considerable caution. Nonetheless, it is important to examine these data (on a relative scale) in order to note possible changes in the character of these parameters over time.
