Bottom sediments were collected with several devices: a PVC corer 

 using a Phleger corer as a trigger weight, a PVC corer used separately, 

 a Phleger corer, an orange peel bucket sampler, and a triangular dredge. 

 The sediment samples were forwarded to Florida State University for 

 analysis. 



Surface biological samples (plankton) were collected with a #5 half- 

 meter net, and bottom fauna samples were taken with a triangular dredge 

 and a crab trap. Plankton samples, preserved in formalin, and fauna 

 samples, either frozen or preserved in formalin or alcohol, were for- 

 warded to the National Museum for analysis. 



Special oceanographic casts were made both years to obtain water 

 samples for geochemistry trace element studies. These one-liter samples 

 were frozen and sent to the Science Council of Japan for analysis. 



Special bottom biological samples were taken during DEEP FREEZE 63 

 for paleoecological investigation by the California Institute of Technology,
