Awalnya ini berfungsi sebagai tempat bongkar/muat material konstruksi pabrik Kaltim. Namun, fungsi tersebut beralih menjadi bahan baku produksi distribusi pupuk urea dengan menggunakan kapal general cargo 2.000 DWT. Wilayah Urea, yaitu wilayah Kalimantan Utara, Tengah, Sela...

Few studies have compared the suitability of different artificial reef construction materials in terms of their efficacy in acquiring diverse faunal assemblages. We compared the fishes associated with 12 co-located reefs constructed of limestone quarry boulders, concrete-gravel aggregate, or concrete-tire aggregate (four of each substrate) in 7 m of water, 200 m offshore Miami Beach, Florida, U...

Highlights Stabilization structures are only effective at stabilized segments. Erosion increased in two of the six segments post-stabilization period. Deposition decreased all Jetties reducing erosion but also prone to fail. Abstract . The effectiveness streambank stabilization is insufficiently quantified. Although such clearly reduce or eliminate local scale, little known about associated eff...

Editor's Note: After reviewing the preceding chapters, EPA's Office of Wetland Protection prepared this concluding chapter, which presents their recommendations for protecting coastal wetlands. Recognizing the numerous benefits and values accrued to society from wetlands, there are several options available for minimizing potential future losses of wetlands from predicted sea level rise. These ...

The chemical and biological impacts of anthropogenic physical modifications (i.e., channelization, dredging, bulkhead, and jetty construction) to tributaries were assessed on New York’s Long Island South Shore Estuary. Water-quality data collected on Carmans, Patchogue, and Swan Rivers from 1997 to 2005 indicate no significant differences in nutrient levels, temperature, or pH among the rivers,...

Crude oil-polluted marine sediment from Bonny River loading jetty Port Harcourt, Nigeria was treated in seven 2.5 l stirred-tank bioreactors designated BNPK, BNK5, BPD, BNO(3), BUNa, BAUT, and BUK over a 56-day period. Five bioreactors were biostimulated with either K(2)HPO(4), NH(4)NO(3), (NH(4))(2)SO(4), NPK, urea or poultry droppings while unamended (BUNa) and heat-killed (BAUT) treatments w...

Tanjung Selongor and Pantai Balok (State Pahang) are the only two places known for spawning activity of the Malaysian horseshoe crab - Tachypleus gigas (Müller, 1785) on the east coast of Peninsular Malaysia. While the former beach has been disturbed by several anthropogenic activities that ultimately brought an end to the spawning activity of T. gigas, the status of the latter remains uncertai...
