The diurnal in DO is a result of algae. When the temperature gets 'too hot' for the algae they begin to die off and we see less of a diurnal in DO. This pattern is seen across all 3 sites, during periods of higher temperatures.<\/li>\n<li>Events that took place on the 06\/08\/2021-10\/08\/2021 show a suppression in DO below 100%. Although it appears to be a small suppression, it is still significant considering the size and dilution factor of the sea. However, this could be caused by wave action, and the sediment having a BOD (Biological Oxygen Demand) associated with it.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>LANDING CRAFT SITE:<\/p>\n<p>Location \u2013 near shore adjacent to Medmerry entrance<\/p>\n<ul>\n<li>Hardly any diurnal variation here, pretty flat lines indicating good water quality probably the best out of the three.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>INNER MULBERRY SITE:<\/p>\n<p>Location: nearshore adjacent to Pagham Harbour entrance<\/p>\n<ul>\n<li>This site has higher DO than the other sites, roughly 15% higher.<\/li>\n<li>Events on the 23\/08\/2021-26\/08\/2021 and 05\/09\/2021-11\/09\/2021 show spikes in temperature and drops in DO.
