Donaldson Applied Fisheries Laboratory University of Washington Seattle 5, Washington Dear lauren: Somehow, under the pressure of producing results for Biology & Medicine, the data on the last survey samples was not forwarded to you. This data has been worked up in Washington, as you probably know. Later results are included in the attached typed sheet. In the tables we do not have information on the wet weight of the Cenobita samples but everything else was complete. There are certain analyses not yet complete and one or two that are being rechecked. Sr?° figures have been obtained at HASL and also at Nuclear Science & Engineering Corp., and at Isotopes, Inc. Another point is the Strontium Units (SU) reported for soil are shown as minimum values. This is because no one can agree on the actual available strontium in a corel soil. Apparently this is very low and the soil SU values are probably two or three orders of magnitude higher than the minimum. I had a chance to talk to Al at a recent meeting in Washington and it looks like we will have some good communication while he is there. He will certainly have his hands full and I would not be surprised to see him trying to get back on board a survey vessel. Sincerely, (Malate Hoey (6 ( Enclosures: 1. Table entitled "UWAFL - Post 2.
