Chapter 8 Ocean Planet

This chapter sets out an overview of how the oceans help to support human society beyond the provision of food. 

Pages 207-208. For a comprehensive overview of the science and technical source material on the role played by coccolithophores in the carbon cycle, material presented by the UK’s National Oceanography Centre is a very good place to start. Go to this web page: http://www.noc.soton.ac.uk/soes/staff/tt/eh/biogeochemistry.html

Pages 208-209. For an accessible overview on the causes and effects of ocean acidification, this presentation by Carol Turley (whom I quote) is a good source: https://webgate.ec.europa.eu/maritimeforum/system/files/Turley_ocean%20acidification%20the%20double%20problem.pdf

Pages 208-209. A more technical overview on ocean acidification can be found in: Longphuirt, S. Stengel, D. O’Dowd, C. & McGovern, E. (2010).

Pages 208-209. An excellent summary on the impacts of elevated atmospheric carbon dioxide concentrations on the oceans can be found in this IUCN document: http://cmbc.ucsd.edu/Research/publications/The%20Ocean%20and%20Climate%20Change_Executive%20Summary.pdf

Page 209. The research that links climate change to the collapse of the southern Caribbean sardine stocks can be found in: Taylor, GT. et al. (2012).

Page 211. On the subject of ‘blue carbon’ and the role played by mangroves, sea grass beds and other ecosystems in carbon cycles, an increasing amount has been written in recent years. This report gives a helpful summary and a good way into the literature: Herr, D. Pidgeon, E. and Laffoley, D. (eds.) (2011).

Page 212. On the economic value of the oceans being about 63 per cent of the total economic value derived from nature, see this famous paper from Robert Costanza and colleagues. The figure is based on the total value of the ocean-related aspects of natural capital and the services provided therefrom: Costanza, R. et al. (1997 The value of the world's ecosystem services and natural capital. Nature 387, 253-260. This paper can be found on-line at: http://www.nature.com/nature/journal/v387/n6630/full/387253a0.html

Page 212-213. For an introduction on the amount of plastic floating in the Pacific Ocean, see this piece from Science Daily. http://www.sciencedaily.com/releases/2012/05/120508220114.htm. Various studies are cited here that can be found on-line, including: M. C. Goldstein et al. (2012). Increased oceanic microplastic debris enhances oviposition in an endemic pelagic insect. Biology Letters, 2012. http://rsbl.royalsocietypublishing.org/content/8/5/817

Pages 214-215. For an introduction on how and why tiny particles of plastic pose threats to some marine ecosystems and species, see: http://www.sciencedaily.com/releases/2012/09/120920082526.htm. Various links to other stories and technical references allow readers to get quite deep into the impacts of plastic pollution in the oceans.

Page 214. I mention work by UNEP and the impact of ocean plastics on the marine environment, including birds and mammals. You can find details in the 2011 UNEP Yearbook. Go there via this link: http://www.unep.org/yearbook/2011/pdfs/plastic_debris_in_the_ocean.pdf This source has some good maps and other figures setting out the scale, scope and causes for this particular problem, including how progressively smaller pieces of plastic attract bioaccumulative toxic materials.

Pages 214-215. Research into the effects of micro-plastic particles on plankton is still at a relatively early stage. An introduction to the literature may be found via: Frias, J. P. G. et al. (2011). Research in plastic marine debris in mainland Portugal. Journal of Integrated Coastal Zone Management 11(1):145-148.

Pages 215-216. For a source on the potential impact of increased jellyfish numbers on fish populations, see: Brodeur, RD. et al. (2008). Spatial overlap and trophic interactions between pelagic fish and large jellyfish in the northern California Current. Marine Biology 154:649–659. This paper can be found at: http://bioweb.coas.oregonstate.edu/~ciannellilab/cameo/articles/brodeur/2008brodeuretal.pdf. These authors state that “Our results suggest that an increase of jellyfish in this system could have profound negative impacts on several commercially and ecologically important components of the ecosystem”.

Pages 215-216. A referenced review of the wider implications of rapid changes in jellyfish populations can be found in: Hay, S. (2006).
