' a+G 4	 The LANDSAT negatives received from NOAA are on material of
Z a v variable thickness.	 When making paper prints for analysis,
^;tl
a
the annotation block information is often lost. 	 Constant
(n c e changes in enlarger focus is necessary when printing a series
I C ~ N of pictures from variable thickness negatives. 	 Some of the
thicker negatives appear to be poorer in resolution than the
( 2-1z
W r `i
e thin films.	 This could brs because of differences in the
Z

'
generation of the contact positives that were used.

E it 1)	 All the LANDSAT 1 and 2 images of San Pablo Bay are being
W a+ N correlated with sediment distribution pattern; measures by the
W
a
• U U.S. Army Corps of Engineers. 	 The Corpa pattern measurements
o ^ are part of a Dredge Disposal Study carried out in the Bay area.
F a y,r As part of this program dredged material was marked with tracer
lNw a r, N	 material and re-introduced at a site off Mare Island where rapid 	
$
it v' v,.r,> dispersal occurs.	 Each month bottom samples were collected at
j a tr, numerous grid points throughout the Bay. 	 Analysis was made to
I u c m	 determine the content of tracer material present. 	 This infor-	 J
VI y o"^ a	 mation was then computerized and geographic plots were wade for

correlation has been found showing that sediment transport
patterns present on the LANDSAT imagery may be utilized in
forecasting bottom sediment distribution patterns.
2) A flight test remote sensing program has been planned for
October to correlate with the LANDSAT overpass. This aircraft
data collection will consist of utilizing various film/filter
combinations for detecting nearshore processes. Simultaneously,
sea truth water column data will be collected for later correlation
with the satellite and aircraft imagery. This flight will take
place in the Santa Barbara-Channel Islands area. This project
is scheduled to collect information from the O,teanic Current
Period along the California coast.
3) Enhancement of coastal current and sediment transport in-
formation utilizing "standard" photographic techniques. Plotting
of current vectors.
4) Plan for utilizing the G.E. Image 100 at the Jet rropulsion
Laboratory for enhancing nearshnre presses. Before this can
commence, pertinent CCT's must ' ordered from NASA.

Use the same thickness of film in making all LANDSAT negatives.
