The dataset contains the presence, and abundance, of benthic invertebrate species at specific marine monitoring points held within the KiECO database. The data was collected using either a Day Grab (0.1 m2) or Hammon Grab (0.1m2) for subtidal samples and either 3 x 0.01m2 cores (Core Diameter 11.28cm) or a Box Corer (0.1m2) for intertidal surveys. Data are laboratory assessed and quality assured following the National Marine Biological Analytical Quality Control (NMBAQC) scheme. 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.

Mae'r data hwn yn coladu'r holl samplau infertebrata benthig a gasglwyd yng Nghymru o 1988 ymlaen gan Cyfoeth Naturiol Cymru ac Asiantaeth yr Amgylchedd Cymru gynt. Gwybodaeth am bresenoldeb a helaethrwydd rhywogaethau infertebrata benthig mewn mannau monitro morol penodol a gedwir o fewn cronfa ddata KiECO. Casglwyd data o fewn y maes gan ddefnyddio naill ai Day Grab (0.1 m2) neu Hammon Grab (0.1m2) ar gyfer samplau islanwol a naill ai creiddiau 3 x 0.01m2 (diamedr craidd 11.28cm) neu digreiddiwr blwch (0.1m2). Asesir data mewn labordy a sicrheir ansawdd yn dilyn y cynllun Rheoli Ansawdd Dadansoddol Biolegol Morol Cenedlaethol. 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 y gwanwyn. 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 ecoleg a data perthynol yn bodoli.
