We present seasonal time series data of chlorophyll <span class=\"italic\">a</span>, primary productivity and in-water irradiance measured in the coastal waters of the Western Antarctica Peninsula and build upon existing models to provide a more optimum parameterization for the estimation of primary productivity in Antarctic coastal waters. These and other data provide strong evidence that bio-optical characteristics and phytoplankton productivity in Antarctic waters are different from temperate waters. For these waters we show that over 60% of the variability in primary production can be explained by the surface chlorophyll <span class=\"italic\">a</span> concentration alone, a characteristic, which lends itself to remote sensing models. If chlorophyll <span class=\"italic\">a</span> concentrations are accurately determined, then the largest source of error (13–18%) results from estimates of the photoadaptive variable (P<span class=\"sup\">B</span><span class=\"sub\">opt</span>). Further, the overall magnitude of P<span class=\"sup\">B</span><span class=\"sub\">opt</span> is low (median 1.09 mg C mg chl<span class=\"sup\">−1</span> h<span class=\"sup\">−1</span>) for these data compared to other regions and generally fits that expected for a cold water system. However, the variability of P<span class=\"sup\">B</span><span class=\"sub\">opt</span> over the course of a season (0.4 to 3 mg C mg chl<span class=\"sup\">−1</span> h<span class=\"sup\">−1</span>) is not consistently correlated with other possible environmental parameters, such as chlorophyll, sea surface temperature, incident irradiance, day length, salinity, or taxonomic composition. Nonetheless, by tuning a standard depth-integrated primary productivity model to fit representative P<span class=\"sup\">B</span><span class=\"sub\">opt</span> values and the relatively uniform chlorophyll-normalized production profile found in these waters, we can improve the model to account for approximately 72–73% variability in primary production both for our data as well as for independent historic Antarctic data.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Optimizing models for remotely estimating primary production in Antarctic coastal waters","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2018-12-19","DateCreate":"2018-12-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000086625500004","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/s0954102000000043"},"refs":null,"anarec":{"AnaID":304215,"PubliDate":2000,"Pagination":"20-32","XtraPublOfAnaID":null,"ISBN":null,"Volume":"12","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45043,"SerRR":"Antarctic Science.
