APPLICATION OF REMOTE SENSING
FOR FISHERY RESOURCE
ASSESSMENT AND MONITORING
INTRODUCTION
This is the tenth of a monthly series of progress reports required by
the statement of work for Project 240 entitled "Application of Remote
Sensing for Oceanic Gamefish Assessment and Monitoring" under Contract
No. T-8217B.
OVERALL STATUS
The post mission analytical phase is in progress with completion required
contractually by June 30, 1974. Submission of a draft copy of the final
report is required 30 days prior to that date in accordance with the
statement of work.
DATA STATUS
During the month, Skylab EREP S190B prints were received. Also, the
S191 tape was received together with the tabulations and graphs, but
may possibly contain erroneous data. The S192 tape (the principle S192
product) is still outstanding, although the calibration tape and screen-
film has been received.
RESULTS
The NC130B multispectral scanner data was displayed on the data analysis
station (DAS) for quick look analysis. Several unsatisfactory channels
are indicated. However the thermal array was functioning and data in
the thermal region appears usable.
The turbidity and chlorophyll models (developed earlier in the analytical
phase and mentioned in previous reports) have been improved by optimizing
wave length selection.
The white marlin distribution model for August 4 and 5 (the period of
field operations and data acquisition) has been improved. The addition
of computed water density values to the model has tended to stabilize the
model coefficients from day to day.
EXPECTED ACCOMPLISHMENTS
Preparation of software to handle S191 data has been delayed but com-
pletion is expected this coming month. Completion of time history plots
of S191 data has also been delayed to the coming month.
Turbidity and chlorophyll contour maps will be prepared from remote
measurements obtained by light aircraft (NASA E-18) spectroradiometer
(E20-1). These will be compared with contour maps prepared from sea
truth values for turbidity and chlorophyll.
Preparation of oceanographic and fishery parameter overlays has been
completed. The overlays will be superimposed on available Skylab
imagery (currently S190A transparencies) for observation of possible
correlations with grey scale density levels.
A technical paper on project results is planned for delivery in April
1974 at a remote sensing symposium at Willow Run, Michigan. An abstract
has been submitted and preparation of the paper is proceeding in accor-
dance with a tentative outline. Submissions to NASA prior to presentation
will be made as required by contract.

SUMMARY OUTLOOK
There has been modest progress in relating the fishery to sea truth and
inferring oceanographic values from satellite/aircraft imagery.
Correlation of the fishery and S190A imagery is in progress. Problems
in Skylab data including tape errors (S191) and delays (S192) are
significantly hampering analysis in the areas of remote sensing/resource
relationships as well as remote sensing/oceanic parameter relationships.
