Hot Brines and Recent Heavy Metal Deposits in the Red Sea A Geochemical and Geophysical Account

Cooperative research ventures between some new ones, such as a telemetering pin­ oceanographic institutions and nations to­ ger for getting a continuous temperature day frequently start with a series of official profile and a thermoprobe accurate to meetings, councils, and so forth, followed 0.005°C. by several years of research, and finally a When the R.

The study of the Red Sea is an around the world for sediment samples to exception to this procedure. It is a good analyze. These requests were filled insofar example of the kind of spontaneous cooper­ as was possible without exhausting all avail­ ation that can occur when individual scien­ able sample. tists get excited about a unique problern and Although the hot brine and heavy metal work together exchanging samples and data deposits cover an area of less than 100 and publishing their final results in a single square miles, they are clearly part of a volume.
