Particulate iron and the nepheloid layer in the western North Atlantic, Caribbean and Gulf of Mexico
Greatly increased concentrations of particulate iron were found within 1000 m of the bottom in the northwest Atlantic and eastern Gulf of Mexico (6 times and 3 to 4 times the average of shallower water, respectively) while only slightly increased concentrations were found within 1000 m of the bottom...

Summary: | Greatly increased concentrations of particulate iron were found within 1000 m of the bottom in the northwest Atlantic and eastern Gulf of Mexico (6 times and 3 to 4 times the average of shallower water, respectively) while only slightly increased concentrations were found within 1000 m of the bottom in the Caribbean and western Gulf of Mexico (2 times the average concentration in shallower water). These distributions agree with published light-scattering studies of deep ocean water, and are hemical evidence of a near-bottom nepheloid layer. It is concluded that the increase in the near-bottom concentrations of particulate iron is not a water mass effect, but arises from interaction of water with the bottom. © 1971. |
