(page 43), Geochemical composition of a phosphatic manganese nodule from Blake Plateau

Mr. John Murray, to whom the specimens of bottom deposits collected by the "Blake" were sent for examination, looked over the whole and selected some typical specimens. These have been described in detail, and he has added some general notes on the specimens characteristic, 1. of the Coast between the Gulf of Maine and Cape Hatteras; 2. of thee coast between Cape Hatteras and Lat. 31? 48' N.; 3. of the coasts around the greater and lesser Antilles ; and, finally, of the Gulf of Mexico and Straits of Florida.

Discarge compilation from The Global River Discharge (RivDIS) Project

The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.
