Following the successful format adopted previously, this new edition treats the oceans as a unified entity, and addresses the question 'how do the oceans work as a chemical system?' To address this question, the text has been updated to cover recent advances in our understanding of topics such as the carbon chemistry of the oceans, nutrient cycling and its effect on marine chemistry, the acidification of sea water, and the role of the oceans in climate change. In addition, the importance of shelf seas in oceanic cycles has been re-evaluated in the light of new research.
Marine Geochemistry offers both students and research workers an integrated approach to one of the most important reservoirs in the Earth System.
Chapter 3 River inputs.
I think most of this section will stay the same with some updating of some fluxes. A few of the tables e.g. 3.4 can probably be simplified, the increase in data may now make it easier to draw a simpler synthesis in this look at trace metals. I'd suggest a bit more on nitrate as an example of large scale human induced perturbations.
The estuarine section I thought might shorten a bit to make room for some of the suggested additions perhaps by having a bit less discussion of some specific examples of estuaries and elements..
Chapter 4 Atmospheric inputs.
This is already a very strong chapter and I'd only plan to update it and perhaps try to synthesise a few of the figures to shorten it slightly and make room for a bit more discussion on nitrogen deposition and on dust transport, since this will be relevant to iron limitation..
Chapter 5 Hydrothermal inputs.
I gather that recent research has significantly modified our understanding of the role and magnitude of these fluxes. This will require a significant rewrite of this chapter..
Chapter 6 Relative Importance of Input Fluxes.
Some of this can be updated, and in particular the changing Pb fluxes over time provide an example of non-steady state responses.
I'd also like to include somewhere, perhaps here some discussion of coastal seas. There are 2 exciting relatively recent issues, one on the relative importance of production and respiration - are they C sources or sinks- the other on their role as N and P sinks - it looks as if in the prehuman world the shelves were N and P sinks for the global ocean, and this may still be the case. This implies that human inputs are less important than appears based on the increases in riverine N and P and really has changed the way I think about these systems and how they are modified by human impact. I think a section on shelf/ocean coupling is also needed..
Chapter 7 Descriptive oceanography.
This is classical/timeless material that will be largely unchanged, unless it can shorten a bit to accommodate new material..
Chapter 8 Dissolved Gases.
The CO2 section can be updated with the now clear evidence of increasing CO2 and linked to ocean acidification here or in the final chapter. I thought there might be a brief additional section on other gases N2O, CH4 DMS NH3 etc of climatic relevance.
Chapter 9 Nutrients, organic carbon and the carbon cycle.
I'd like to include a bit more on phytoplankton seasonality and difference with latitude and season, on changing concepts of nutrient limitation and further evidence for Fe's role as a nutrient and for variable elemental (Redfield ratios).
Our understanding of DOC is now much better and the role of DON and DOP are becoming clearer. This material will need updating but the clearer picture now available may mean the sections needn't get longer because the patterns seen are becoming more logical.
The importance of nitrogen fixation will need to be considered since this has undergone quite a revision over the last 5 years.
The sections on organic compounds will need updating but my preference is to not expand this greatly with discussion of individual compounds but to consider ways oceanographers have used specific compounds to trace particular processes..
Chapter 10 Particulate Matter.
It may be sensible to merge this with chapter 12 Most of the content in chapter 10 seems still up to date but
