Preliminary study of marine environmental parameters in the southeastern coastal area of Bali, Indonesia

Abstract

Southern part of Bali island is famous for its fascinating area, so many marine tourism activities and coastal settlements exist in this area. Therefore, a preliminary monitoring may be beneficial to see the current sea condition around this area. Three places are considered, namely Nusa Dua (ND), Sanur (SN), and Nusa Lembongan (NL). Field activity consists of measuring ocean parameters and collecting water samples which was carried out on 30 September-4 October 2022. Ocean parameters investigated such as temperature, salinity, pH, turbidity, DO, and heavy metal (Cd, Cu, Ni, Pb, Hg). Additional data of physical oceanography from secondary data or references also w taken into account. The measurement data compared to see its conformity with the national standard of seawater for marine tourism. Based on the result, most of the parameters are within the threshold and still considered as good condition.
