Late Holocene diatoms in sediment cores from the Gonggeomji Wetland in Korea

New recorded diatoms in Holocene sediment cores from the Gonggeom-ji Wetland in Korea

“…Since Gonggeom-ji has a very high historical value, many related studies are also being conducted, such as research on understanding the construction period and the land and aquatic environment around Gonggeom-ji ( Kim et al 2017 ; Lim et al 2011 ). The Nakdonggang National Institute of Biological Resources conducted diatom, geological, and depth distribution analyses on the sedimentary soil of Gonggeom-ji in 2019 and 2020 and recently revealed the size of the reservoir (Lee et al 2020a , b ). Diatoms, which played an important role in determining the size of Gonggeom-ji, are single-celled eukaryotic groups of microalgae called yellow or golden algae (Falciatore and Bowler 2002 ; Mann et al 2010 ).…”

“…In Korea, fossil diatom research began in the early 1970s and still continues today. However, diatom research in the freshwater wetland sedimentary layer remains lacking (Lee 1996 ; Lee et al 2020a , b ), and most studies on domestic wetlands and sedimentary layers have focused on geology and pollen (Yi et al 2005 ; Yoon et al 2008 ). Our study aimed to summarize the description and ecological characteristics of newly recorded diatoms ( Gomphonema lacusrankala, Pinnularia diandae, P. gibba var.…”

Identification of New Sub-Fossil Diatoms Flora in the Sediments of Suncheonman Bay, Korea

“…The sub-fossil diatoms herein described consist of Holocene diatom remains not fully involved in the fossilization process. Diatoms thrive in very different environments (e.g., hot springs, polar regions, and fresh, brackish, and marine waters) and are extremely sensitive to physical and chemical changes (e.g., temperature, salinity, and nutrients) in the water [18][19][20][21][22][23]. Therefore, fossil diatoms represent an excellent source of information about past climate change and its effect on aquatic ecosystems.…”
