Data for: A Revised Sea Level History for the Northern Strait of Georgia, British Columbia, Canada
Description
Counts of diatom species from terrestrial and marine sediment basins. The table documents counts of diatom species identified from sediment cores recovered from Quadra and Read islands, British Columbia, Canada. From Quaternary Science Review submission: Observed diatom floras were compared to those identified in Campeau et al. (1999), Cumming et al. (1995), Falu et al. (2000), Foged (1981), Hein (1990), Kelly et al. (2005), Pienitz et al. (2003) and Spaulding et al. (2010). Following Hustedt (1953), diatoms were assigned to five salinity classes: 1 - halophobian (fresh, salt intolerant), 2 - oligohalobous indifferent (freshwater), 3 - oligohalobous halophilous (freshwater species tolerant of salinity to 0.2 ppt), 4 - mesohalobous (brackish water species with optimal salinity between 0.2 and 30 ppt) and 5 - polyhalobous (marine water species with optimal salinity greater than 30 ppt).The salinity tolerance of identified floras was determined using the latter diatom flora references and data from Denys (1992), Guiry and Guiry (2017), Hustedt (1953), Marohasy and Abbot (2007), Wilson et al. (1996) and Zong and Sawai (2015)
