Title: Hersey, 1967: Deep Sea Photographs

Abstract:

This book contained various data obtained in the course of miscellaneous expeditions to develop and use underwater cameras to examine the seafloor. Please note that for the purposes of the usSEABED data collection, some data in this data set was created at the time of data entry by interpretation of the printed seabed images with the assistance of captions included in the original book.

1. How should this data set be cited?

   Jenkins, Chris, 2005, Hersey, 1967: Deep Sea Photographs.

4. Does the data set describe conditions during a particular time period?

   Calendar_Date: Various, pre-1967

   Currentness_Reference: ground condition

5. What is the general form of this data set?

   Geospatial_Data_Presentation_Form: document

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (5)

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.

Seafloor camera development

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

   (process 1 of 2)

   The data was typed into and checked in EXCEL format, then exported to dbSEABED format. Some data was created at the same time by interpretation of the printed seabed images with the assistance of captions.

   (process 2 of 2)

   Digital data were checked, formatted to dbSEABED input format, then processed using dbSEABED software to produce a range of output formats. The processing contained quality checking that may have declined to pass faulty or suspect data to outputs.
