Plankton Changes on the Coast of Ecuador


MR. G. SHEPHERD directs attention in NATURE of April 25 to the masses of yellowish brown plankton matter seen off the coast of Ecuador. Some years ago the Chilian coast experienced a similar visitation, with much resulting trouble to locomotive boilers and condensing plant. I had some of the water with the brown contents sent home and forwarded for examination to the Marine Biological Laboratory at Plymouth, where it was investigated and the results were kindly communicated to me.
