The flora in the region of Daeheuksando ($N34^{\circ}37^{\prime}{\sim}34^{\circ}42^{\prime}$, $E125^{\circ}23^{\prime}{\sim}125^{\circ}38^{\prime}$) was surveyed from June 2010 to October 2011. The vascular plants from 22 field surveys were revealed to total of 496 taxa: 113 families, 316 genera, 446 species, four subspecies, 43 varieties and three forms. 124 taxa were the first records from this region. This field study discovered significant plants in various categories. Korean endemic plants numbered 7 taxa, and 6 taxa designated by Korean Forest Service as rare plants were investigated in this region. The taxa in the category II of rare and endangered plants and higher than the third degree among the floristic regional indicator plants designated by Korean Ministry of Environment were one taxon and 47 taxa, respectively. Especially, it was proved that Spiraea chartacea, Hosta yingeri, Hemerocallis hongdoensis and Saussurea polylepis were endemic to Heuksan-myeon including Daeheuksando in Korean peninsular. In addition, the naturalized plants of 46 taxa were recorded.

This work represents results of analysis of tidal observations at twelve major ports(Inchon, Kunsan, Mokpo, Daeheuksando, Jeju, Yeosu, Jinhae, Busan, Pohang, Ulsan, Mugho, Sogcho) around Korean coast for the years up to 1979. The reduction of hourly tide gauge sea level records provided by Korean Hydrographic Office was performed in systematic manner resulting digitised hourly observed series, predicted series and residual series. As a first step the application of an extended harmonic method of analyzing the tidal observations leads to the identification of 42 new constituents including 60 orthodox Doodson's constituents at major ports. The sea level statistics including sea level frequency distribution are presented and the tidal emersion curves showing the percentage of time for which different levels are covered by water and exposed are also presented to provide useful design input for coastal development. This study has teen undertaken in association with the programme of sea level research at Korean Hydrographic Office and the programme of adjustment of first order levelling network at National Geographic Institute.
