Tide pools are known to have extreme variations in both their temperature and
carbonate chemistry while they are isolated from the surrounding waters. These extreme
environments provide an interesting view into how organisms are able to cope with large
variations in temperature, pH and total carbon. The knowledge of how organisms cope
with high temperature and low pH conditions will be beneficial when contemplating how
organisms will deal with the conditions that are expected to come from global warming
and ocean acidification in the not-too-distant future. In this study we observe several
physical and chemical characteristics of two tide pools, comparing them to each other as
well as to the waters surrounding them. We then manipulate one of the tide pools (by
adding photosynthesizing organisms on one day and respiring organisms on the next day)
in order to observe the biological impact on the carbon chemistry of a tide pool.
