Indonesia is an archipelagic country with a vast coastal area, so proper management needed in the development of areas. The city Surabaya one cities that carry out areas by projecting strategic its as regulated regional medium-term plan 2016-2021. area divided into two, namely to support economic growth and save environment. One efforts optimize examine changes morphology due utilization. Analy...

Coastal erosion is the process of land in coastal areas due to waves and ocean currents which reduce can adversely affect socio-economic activities areas. risk assessment estuary a development previous research, because accretion processes do not only occur along shoreline, but also on side facing river water bodies, confluence fluvial marine processes. The landward shift shoreline Muara Asam a...

Problem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. A study was conducted in order to explain t...

The aim of this study was to determine pollution by polycyclic aromatic hydrocarbons (PAH) and heavy metals in seawater and sediment in Kostrena coastal area, as well as their toxicity using bioluminescence based tests. Total PAH concentration in seawater ranged 1.7-155.3 ng/L. The share of carcinogenetic PAH was relatively high, ranging 22-48.3%. Nickel concentrations in seawater were beyond d...

Beached bird surveys have been widely used to monitor the impact of oil pollution in the oceans. However, separating the combined effects of oil pollution, environmental variables and methodological aspects of beach monitoring on seabird stranding patterns is a challenging task. The effects of a comprehensive set of oceanographic and climatic variables and oil pollution on seabird strandings in...

The transport of nitrate into the euphotic zone is an important regulator of primary production. This transport is facilitated by physical processes that involve the depth and the steepness of the nitracline, but transport is complicated by the dynamical nature of the euphotic zone. Here we derive an analytical model that predicts two optical effects of the euphotic zone on the nitracline: the ...
