Objectives: (Reference NASA Contract S-70253-AC dated 14 June 1972):
* Analyze and map the sediment deposition in harbors, inlets
and docking facilities in the Cook Inlet.
* Map the permafrost areas of Alaska as inferred by vegetative
patterns. Compare major tonal and textural permafrost
patterns with Mariner imagery.
t* Correlate the snow pack cover of Caribou-Poker Creek with
stream runoff.
* Map and inventory the icing of the Chena River.
* Items 2 and 4 above are to be correlated with the University
of Alaska studies in the same area.
Accomplishments:
Three cycles (Nos. 23-25) were completed over Cook Inlet during this
reporting period. Only one image (1410-20563) acquired on 6 September
1973 was useable and interpretations based on this frame verified
earlier findings. All except the central portion of the inlet was cloud
covered. The shape of the plumes from the Kasilof, Drift and Big Rivers
indicates that the water at tAe river mouths is moving north into the inlet.
This northerly flow occurred during mid-flood tide (maximum high water
occurred at 2:09*). The intrusion of clear, saline water which occurs
during flood tide, as previously reported **, was observed. The clear
oceanic water remains as a distinct water mass to the approximate
latitude of Kenai. At this location mixing with the sediment laden inlet

water produces a zone of mixed water. Bottom scouring and sediment reork-ing
may also cause some of the apparent differences in suspended sediment
concentration west of Kenai.
The 9.5"x 9.5" color prints have better tonal characteristics for
vegetation maping than B/ prints and were therefore used to corroborate
the distribution of vegetation in selected areas of the 59,000 square mile
area in north central Alaka (reference Third Type 1 Report, dated 23
February, 1973.)
Work to be acccr l.ished next renortin7 neriod:
Imagery of the Cook Inlet area will be analyzed and interrretations
compared to earlier findings. Detailed analysis of the tT;o terrestrial
thermokarst areas considered analo-ous to some of the ?fartian terrain
will continue. Work will begin on the preparation of the Type III,
Final Renort.
