A Comparison of Carbon Isotopes and Cadmium in the Modern and Glacial Maximum Ocean: Can We Account for the Discrepancies?
Carbon Cycling in the Glacial Ocean: Constraints on the Ocean’s Role in Global Change, 1994

Some differences between the distributions of these properties are seen in the modern ocean, although these differences can be rationalized. In the glacial maximum (18K) ocean, the differences between benthic foraminiferal δ13C and Cd/Ca are much larger than in the modern ocean, suggesting quite different scenarios for the carbon system chemistry of the Southern Ocean, the northwest Pacific Ocean, and the intermediate waters of the Pacific. A reexamination of the modern distribution of δ13C and Cd suggests that one major factor which has not been addressed in detail is the role of gas exchange on δ13C, but it is not clear that this factor can reconcile the differences between the tracers during the glacial maximum. The modern oceanic Cd-P relationship is reassessed in light of three new data sets and found to be consistent with previous interpretations of deep ocean data. The issue of foraminiferal accuracy and precision for δ13C and Cd/Ca reconstructions is considered: more effort on living benthic foraminifera is clearly needed to resolve the uncertainties concerning foraminiferal response to bottom water properties.

Of these, only Pb has a well documented history of this increase based on atmospheric flux estimates, ocean water column measurements, and historical archives such as corals and ocean sediments. Most of the Pb in the ocean today is from human emissions. Sedimentary and ice core archives and atmospheric measurements document the Hg increase, but accurate water column measurements are available only recently. For other elements, there are clear increases in some archives and in coastal environments, but not for the open ocean.

It is fashionable to criticize tourism, but it is one way that local people can benefit from being associated with these amazing ecosystems without threatening their unique biodiversity. These excellent books bring working scientists and students up to date on the character and perhaps the sad ultimate fate of ancient lakes. Both would be a fine addition to any limnological library and will serve admirably to stimulate research on, and concern for, these precious ecosystems.
