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 Darwin Core version of this data which is published to the NBN Atlas is available in NRW_DS161379.

A basic understanding of relational data is assumed. 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.

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. Golygiadau Mae rhywfaint o wybodaeth wedi’i golygu i sicrhau bod y data ar gael yn agored. Mae hyn yn cynnwys: Data trydydd parti Data a gasglwyd ar gyfer ymchwiliadau parhaus Arolygon wedi’u canslo neu heb eu cwblhau Amlder Diweddaru Mae'r data hwn yn cael ei ddiweddaru'n barhaus gyda'r rhan fwyaf o'r newidiadau'n cael eu gwneud yn gynnar yn yr hydref. Yn aml, nid yw data o dymhorau arolygon yn cael eu mewnbynnu ar adeg eu cipio a gall fod sawl mis cyn iddo gael ei roi yn y system. Mae'r set ddata allanol yn cael ei diweddaru'n fisol i gynnwys data newydd, a gall hefyd gynnwys cywiriadau i ddata a gyhoeddwyd yn flaenorol oherwydd gwaith sicrhau ansawdd. Rhybuddion Gwybodaeth Mae arolygon yn cael eu cynnal gan ystod o ddulliau arolygu ac nid yw'r data o un arolwg o reidrwydd yn uniongyrchol gymaradwy ag un arall. Argymhellir bod y defnyddiwr yn gwirio'r dull arolygu a ddefnyddiwyd yn y data a ddarperir. Gwnawn ein gorau i osgoi problemau ansawdd data, ond gan fod y setiau data hyn yn adlewyrchu’r data sydd gennym, gallant gynnwys gwallau. Darperir y data fel set o dablau data cysylltiedig oherwydd maint a strwythur y data. Tybir bod dealltwriaeth sylfaenol o ddata perthynol yn bodoli. Arweiniodd y newid mewn labordy dadansoddol yn 2010 at y labordy newydd yn adrodd am fwy o helaethrwydd o rywogaethau oherwydd y microsgopau mwy pwerus ar gael. Roedd anghysondebau hefyd o ran cofnodi ffaeocystisfel naill ai cyfrif celloedd neu gyfrif cytref.
