This report provides an update of the previous time-series data to include continuous results from January 2013 through May 2014. Ten taxa constituted ~95 percent of both the 2013 and 2014 assemblages: Globigerinoides ruber (pink and white varieties), Globigerinoides sacculifer, Globigerina calida, Globigerinella aequilateralis, Globorotalia menardii group [The Gt. menardii group includes Gt. menardii, Gt. tumida, and Gt. ungulata], Orbulina universa, Globorotalia truncatulinoides, Pulleniatina spp., and Neogloboquadrina dutertrei. In 2013, the mean daily flux was 177 tests per square meter per day (m\u22122 day\u22121), with maximum fluxes of >1,200 tests m\u22122 day\u22121 during the middle of February and minimum fluxes of <13 tests m\u22122 day\u22121 during the beginning of November. In 2014, the mean daily flux was 189 tests m\u22122 day\u22121, with maximum fluxes of >900 tests m\u22122 day\u22121 at the end of January and minimum fluxes of <30 tests m\u22122 day\u22121 at the beginning of January. Globorotalia truncatulinoides showed a clear preference for the winter, consistent with data from 2008 to 2012. Globigerinoides ruber (white) flux data for 2012 (average 23 tests m\u22122 day\u22121) were consistent with data from 2011 (average 30 tests m\u22122 day\u22121) and 2010 (average 29 tests m\u22122 day\u22121) and showed a steady threefold increase since 2009 (average 11 tests m\u22122 day\u22121) and a tenfold increase from the 2008 flux (3 tests m\u22122 day\u22121). The flux data from 2013 (average 15 tests m\u22122 day\u22121) and 2014 (average 8 tests m\u22122 day\u22121) showed decline from the previous 3 years.", "description": "Report: iv, 14 p.; Table", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Reynolds, Caitlin E. creynolds@usgs.gov", "givenName": "Caitlin E.", "familyName": "Reynolds", "email": "creynolds@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-1724-3055", "url": "https://orcid.org/0000-0002-1724-3055"}, "affiliation": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}, {"@type": "Person", "name": "Richey, Julie N. jrichey@usgs.gov", "givenName": "Julie N.", "familyName": "Richey", "email": "jrichey@usgs.gov", "affiliation": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}], "funder": [{"@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc"}]}
