tblDiveEvent
PURPOSE: The dive event table documents all relevant information about each dive survey conducted. The attributes of the dive are described including the geographic position to ensure that each dive meets all of the sampling guidelines. Each successful dive will generate a record containing data used to describe the characteristics of the dive in terms of the latitude, longitude, date, sampling organization and what surveys were conducted at the time of the dive.
TABLE GUIDELINES:
-
The combination of the fields StationID, SampleDate, SamplingOrganization, Replicate, Side and DepthZone ensure unique values for each record in the table.
-
This file can be named at the discretion of the user; however the excel sheet tab must be named tblDiveEvent for submission to the Bight 08 online system.

tblDiveFishAbundance
PURPOSE: The purpose of the dive fish abundance table is to document the number of individuals in each size class in each species from four replicates within each depth zone. Each record represents the number of fish in a particular size class of a particular species.
Fish are counted and their sizes (total length) estimated to the nearest cm in small fish and the nearest 5cm in larger fish (>15cm).
TABLE GUIDELINES:
-
The combination of the fields StationID, SampleDate, SamplingOrganization, DiveReplicate, DepthZone, Level, Species and SizeClass will ensure that each record is unique in the table.
-
This file can be named at the discretion of the user; however the excel sheet tab must be named tblDiveFishAbundance for submission to the Bight 08 online system.
