This methodology is based on the principle that additional nutrients (especially nitrogen) can alter the amount of phytoplankton in transitional and coastal waters. Persistent and high counts of phytoplankton taxa are also seen as a measure of disturbance in the phytoplankton community. These surveys are conducted as part of on-going monitoring for legislative requirements and to meet organisational drivers. In addition, sites may be sampled for investigative work, or on an ad hoc basis. Phytoplankton samples are taken in situ and are usually sent to a specialist marine contractor for Species Identity and abundance (two labs have been used in this time period; CEFAS 2007 – 2009 & APEM 2010 – onwards). Phytoplankton samples are analysed (identified and counted) using the Utermöhl method. Further information is available from the UK-TAG WFD website. For many of our marine survey techniques we record an NGR at the site because this acts as a central/representative location around which we collect lots of samples. An NGR is then also recorded against each of the samples to give a more accurate sampling location.

A geospatial version of this data is available in NRW_DS124916 Mae'r data hwn yn coladu'r holl samplau ffytoplancton a gasglwyd yng Nghymru o 2007 ymlaen gan Cyfoeth Naturiol Cymru ac Asiantaeth yr Amgylchedd Cymru gynt. Mae'r fethodoleg hon yn seiliedig ar yr egwyddor y gall maetholion ychwanegol (yn enwedig nitrogen) newid faint o ffytoplancton sydd mewn dyfroedd trosiannol ac arfordirol. Mae cyfrifon cyson ac uchel o dacsonau ffytoplancton hefyd yn cael eu gweld fel mesur o aflonyddwch yn y gymuned ffytoplancton. Cynhelir yr arolygon hyn fel rhan o waith monitro parhaus ar gyfer gofynion deddfwriaethol ac i fodloni ysgogwyr sefydliadol. Yn ogystal, gellir samplu safleoedd ar gyfer gwaith ymchwiliol neu ar sail ad hoc. Cymerir samplau ffytoplancton yn y fan a'r lle ac fel arfer cânt eu hanfon at gontractwr morol arbenigol ar gyfer nodi’r rhywogaeth a’i helaethrwydd (defnyddiwyd dau labordy yn y cyfnod hwn; CEFAS 2007 – 2009 ac APEM 2010 – ymlaen). Mae samplau ffytoplancton yn cael eu dadansoddi (eu nodi a'u cyfrif) gan ddefnyddio'r dull Utermöhl. Ar gyfer llawer o'n technegau arolygon morol, rydym yn cofnodi Cyfeirnod Grid Cenedlaethol ar y safle oherwydd mae hwn yn gweithredu fel lleoliad canolog/cynrychioliadol yr ydym yn casglu llawer o samplau o'i gwmpas. Yna mae Cyfeirnod Grid Cenedlaethol hefyd yn cael ei gofnodi yn erbyn pob un o'r samplau i roi lleoliad samplu mwy cywir.

The change in analytical lab in 2010 resulted in the new laboratory reporting increased abundances of species because of the more high-powered microscopes available. There were also inconsistencies in recording Phaeocystis as either cell counts or colony counts.
