The purpose of this paper is to demonstrate the dangers of doing so through a comparison of reprocessed MODIS Terra and Pathfinder v5.2 SSTs, both at 4 km resolution, with instrumental <em>in situ</em> temperatures taken within 400 m from the coast. We report large biases of up to +6°C in places between satellite-derived and <em>in situ</em> climatological temperatures for 87 sites spanning the entire <em>ca</em>. 2 700 km of the South African coastline. Although biases are predominantly warm (i.e. the satellite SSTs being higher), smaller or even cold biases also appear in places, especially along the southern and western coasts of the country. We also demonstrate the presence of gradients in temperature biases along shore-normal transects — generally SSTs extracted close to the shore demonstrate a smaller bias with respect to the <em>in situ</em> temperatures. Contributing towards the magnitude of the biases are factors such as SST data source, proximity to the shore, the presence/absence of upwelling cells or coastal embayments. Despite the generally large biases, from a biogeographical perspective, species distribution retains a correlative relationship with underlying spatial patterns in SST, but in order to arrive at a causal understanding of the determinants of biogeographical patterns we suggest that in shallow, inshore marine habitats, temperature is best measured directly.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A coastal seawater temperature dataset for biogeographical studies: large biases between <i>in situ</i> and remotely-sensed data sets around the coast of South Africa","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2021-09-13","DateCreate":"2021-09-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000327947800072","VABBcode":null,"OpenAcc":1,"DOI":"10.1371/journal.pone.0081944"},"refs":null,"anarec":{"AnaID":344794,"PubliDate":2013,"Pagination":"e81944","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":123954,"SerRR":"PLoS One.
