“…It is used for fisheries and marine tourism activities, and its land area is dominated by tourism, fisheries, fishermen's settlements, and mangrove forests [13]. It can also be noted that the eddy current in the middle of Madura Strait affects chlorophyll-a concentration in the coasts around Madura Strait, including the eastern part of the Surabaya coast [14].…”

Surabaya’s coasts, situated in an active metropolitan region, threatened by metal contamination, which can be found in particulate matter. However, data of suspended particulate matter (SPM) and particulate metals on the Surabaya Coast are scarce. This study aims to systematically evaluate the impact of trace metals on the environment through particulate metal analysis. Water sample was taken in May 2017 at 17 sites, and analyzed using the acid digestion procedure and measured by ICP-MS. The results show that SPM levels range from 10.80 – 51.80 mg/L, while the concentrations of particulate metals range from 0 – 2.78 mg/kg, 1.14 – 130.77 mg/kg, 3.43 – 60.19 mg/kg and 0.87 – 7.00 mg/kg dry weight for Cd, Cu, Pb, and As, respectively. The location of Surabaya coast might affects salinity and temperature where eastern part is more affected by Madura Strait, but metal concentration are all affected by riverine input. Based on the Geo-accumulation Index and Pollution Load Index, several sites on the Surabaya’s coasts are polluted. However, they have low-level toxicity and insignificant mortality, indicating the Surabaya Coast environments is still safe for living habitat. Meanwhile, particulate metal concentrations are relatively high in several locations, possibly caused by the port, marine tourism, and other anthropogenic activities.

Chlorophyll-a (Chl-a) is a type of pigment is most common and predominant in all oxygen-evolving photosynthetic organisms such as higher plants, red and green algae. The concentrations of high chlorophyll-a (Chl-a) in coastal waters tend to be lower offshore due to land through river water runoff. The Madura Strait is one of the Indonesian basins that is widely used for fisheries activity, which directly impacts and puts quite high pressure on the aquatic resources. In addition, the development of urban areas and changes of land use in the hinterland areas of East Java Province due to increasing population are also intensive. The objectives of this research were: (1) to map the distribution of chlorophyll-a, its concentration and dynamics in the Madura Strait near the Pasuruan coastal area using remote sensing for both dry and rainy seasons, (2) figure out the influence of rivers or other oceanographic factors that may occur, and (3) calculate the accuracy of the estimation compared to the field data. The Landsat 8 OLI imagery was used to determine the concentration of Chl-a and analyze its seasonal spatial distribution pattern. The results show that (1) spatial distribution of chlorophyll-a (Chl-a), its concentration and dynamics in the Madura Strait waters near the Pasuruan coastal area varies between dry and rainy months or seasons, (2) input from rivers, waves, tidal level, and eddy circulation constitute the oceanographic parameters that influence the spatial distribution pattern of chlorophyll-a (Chl-a) in the Madura Strait waters near the Pasuruan coastal area, and (3) validation of the estimated Chl-a concentrations from Landsat 8 OLI using field data has shown RMSE value of 0.49.
