  • A field experiment of the leeway of person-in-water(man with wetsuit) was conducted during October 1997∼ April 1998. The experiment area was northeast side of Cho Do island in Pusan. The college students whose weight ranges 60∼87 kg, height 170∼178 cm were actually drifted for the experiment. The person-in-water wore 5 mm neoprene diving wetsuit to prevent heat loss of the body. The current near the target was measured using a colored vinyl bag. To compare the result a scuba diver equipped with scuba gear and with his BC(buoyancy compensator) fully inflated was drifted alongside. The average leeway speed of man with wetsuit and that of scuba diver were about 0.4 percent and 1.3% of the 10 m wind speed above the water respectively.

  • This study introduces a newly discovered brittle star, Amphiophiura megapoma, from the mesophotic zone in the East Sea, Korea. It is the second species belonging to the genus Amphiophiura (which includes 57 species) to be recorded in Korean waters after A. sculpta. The specimen was discovered during a September 2022 survey, by SCUBA diving in the upper mesophotic zone of the East Sea, Korea. This study presents the morphological characteristics of A. megapoma, highlighting its differences from the related species within a comprehensive taxonomic description. It provides high-resolution images of A. megapoma and a taxonomic key for Amphiophiura species in Korea.

  • A taxonomic study on marine sponges was conducted with materials collected from Gageodo Island, Korea, from August 1999 to July 2001 by SCUBA diving. Among them, Phorbas gukhulensis n. sp. is new to science. Phorbas gukhulensis n. sp. is similar to P. fitictius Pulitzer-Finali from which it differs in spicule size and growth form.

  • A taxonomic study on Hoplophrys oatesii Henderson, 1893 was conducted with materials collected from Jejudo Island of Korea by SCUBA diving. H. oatesii is redescribed with some remarks on variations of dactylus and the number of segments of abdomen. The Korean Pisid fauna now consists of seven species of five genera.

  • Some hydroid specimens were collected from Jejudo Island (Seogwipo, Biyangdo, Marado, Mundo) by SCUBA diving. They were identified into Pennaria disticha Goldfuss, 1820 of the order Athecatae, and Hydrodendron leloupi Hirohito, 1983; Nemertesia ciliata Bale, 1914; Haliaria vegae $J\"{a}derholm$, 1903 of the order Thecatae. They were new to the Korean fauna.

  • Eighteen species of fish were identified by SCUBA diving observations around experimental artificial reefs at Tongyeong marine ranching area between November 1998 and November 1999. The highest species number of 14 was observed in September while the lowest number of 2 was observed in November. Fishes showed three typical behavioral patterns against the experimental artificial reef.

  • A new species of bryozoan, Bicellariella fragilis n. sp. is reported from Jejudo Island, Korea. It was collected at Munseom I. and Supseom I. off Seogwipo city by the fishing net and SCUBA diving from 1978 to 2009. The new species has characteristics of four to five dorso-distal spines and two proximal spines, whereas ten to twelve spines of B. sinica are not separated into two groups of the distal and proximal ones. And this species shows the difference from B. levinseni in having no avicularium.

  • Jeju Island, because of its location off the south coast of the Korean peninsula, has a varied marine mollusk fauna, As part of a continuing effort to enumerate and study the mollusks of the island, extensive SCUBA diving surveys have been done in the Sogwipo area, particularly around the islets of Munsom, Pomsum, and Supsum.
