The diversity and biomass distribution of benthic diatom flora at tidal flats of Hampyeong Bay were studied from 2006 to 2013 as a part of KLTER Program. A total of 83 species (77 strains in 2006, 65 strains in 2007, 41 strains in 2008, 45 strains in 2009, 54 strains in 2010, 55strains in 2011, 56 strains in 2012 and 40 strains in 2012) were identified as benthic diatoms of Hampyeong Bay tidal flats. The most dominant species were Paralia sulcata and Cyclotella litoralis.
Cyclotella sp., Diploneis sp., Entomoneis alata, Gyrosigma sp., Navicula abunda, Navicula gregaria,Navicula spp. and Nitzschia palea were the other common species which contributed to the high benthic diatom biomass in the Bay. The diversity of benthic diatoms varied according to the sample stations and seasons. The highest diversity was observed in August samples. The range of chlorophyll-a concentration in sediments of tidal flats for 8 years was 21~65 mg m‑². The standing crops of benthic diatoms varied according to the studied stations and sampled seasons. The number of taxa and standing crops showed decreasing tendency year after year from all sampled stations. The distributions of standing crops and cell volumes of benthic diatoms showed similar pattern. The taxa and biomass of benthic diatoms showed low correlation coefficients with temperature variables expressed as the following equations Y=- 0.0208X²+0.5264X+19.529 (r²=0.0269) and Y=-0.9181X²+27.011X+310.07 (r²=0.0797) respectively.
