Geoarchaeology, Volume 36, Issue 6, Page 875-896, November/December 2021., 2021 Abstract Elevated concentrations of total mercury (THg) are found in the surface soils and flanking wetland sediments at the Classic Maya coastal site of Marco Gonzalez, Belize. Significant concentrations (up to 1.3 µg·g−1 dry mass) of THg occur in leaf litter‐rich soils, as well as in the artefact‐rich anthrosol spread over the vegetated mound site of

Journal of Geophysical Research: Oceans, Volume 126, Issue 6, June 2021., 2021 Abstract We evaluated the contribution of net biological effects (photosynthesis + respiration + decomposition) to the carbonate parameters and air–water CO2 fluxes in Tokyo Bay, Ise Bay, and Osaka Bay in Japan. The carbonate parameters (fugacity of CO2, total alkalinity, and dissolved inorganic carbon) were measured mainly by cargo ships traveling ...

Notes on feeding of Chaetognatha in Guanabara Bay, Brazil [PDF]
Journal of Plankton Research, 1997 A preliminary analysis, by means of the gut content, of the diet of Sagitta friderid and Sagitta enflata occurring in Guanabara Bay was carried out. The samples were collected at different times over a 4 day period in September 1995, during vertical tows with a conical net of 200 um mesh size at a fixed station (30 m depth).
