Abstract The impact of submarine hydrothermal systems on organic carbon in the ocean—one of the largest fixed carbon reservoirs on Earth—could be profound. Yet, different vent sites show diverse fluid chemical compositions and the subsequent biol

This is the first report of transparent exopolymer particle (TEP) concentrations within deep-sea hydrothermal vent systems using colorimetric methods, measuring TEP in supernatants of sediments surrounding the vents, in fluids emanating directly from

Marine-snow aggregates are compositionally diverse macroparticles that dominate the vertical material flux in many open-ocean environments. There is little documentation of the detailed physical structure and microcomposition of marine-snow aggregate

The morphological variation in bacterial capsules found in suspended and sinking particles from the open ocean is examined. The capsules consist of matrices of mucopolysaccharides that remain attached to and extend the cell surface. Transmission elec

The in vivo accumulation rate of 210Po by Macrocystis pyrifera (L) Ag. has been determined by the tagging of specific parts of young, growing lamina in La Jolla kelp beds and their subsequent collection for 210Po analysis. The rates of accumulation f

Polonium can be electrodeposited onto carbon rods directly from acidified seawater, stripped from the rods, and autoplated onto silver counting disks with an overall recovery of tracer of 40 +- 2 percent for an electrodeposition time of 16 h, 61 +- 6
