The storm tides, surges, and waves that are associated with typhoons/tropical cyclones/hurricanes the most severe threats to coastal zones, nearshore waters, navigational safety [...]

Phycoerythrin (PE) spectral diversity was investigated in eastern tropical Australian waters and around New Caledonian and Fijian archipelagos. Colony sorting of filamentous cyanobacteria revealed slight differences in the PE excitation spectrum of Trichodesmium thiebautii and T. erythraeum. Spectra of PE from Katagnymene spiralis and Richelia intracellularis were examined for the first time. P...

This work aims to extract optical parameters of coastal sea water with high sediment and chlorophyll content by fitting reflectance spectra to a model. Sea-truth water sampling campaigns were carried out from Dec 1996 to Dec 1999 in coastal waters around Singapore. In-situ reflectance spectra were acquired using a portable spectroradiometer. Laboratory measurement of the total suspended solid (...

Porpita porpita occurs in the tropical and sub-tropical waters of Pacific, Atlantic, Indian Oceans, mass numbers stranded colonies seem to be increasing. Although its presence is minimal, this first record ever made P. Visakhapatnam coastal waters. The present study provided a detailed description species global distribution. Further, perceived increase gelatinous zooplankton blooms observed ar...

To elucidate trends of hypolimnetic oxygen concentrations, vertical distributions of dissolved oxygen were measured in eight deep tropical bodies of water (one natural lake with two basins, five natural lakes, and one reservoir) in Indonesia. A comparison of those concentrations with previously reported data revealed that shoaling of hypolimnetic oxygen-deficient (around a few decimeters to a f...

Tropical coastal waters are highly dynamic and amongst the most biogeochemically active zones in ocean. This review compares nitrogen (N) phosphorus (P) cycles temperate tropical waters. We literature to identify major similarities differences between these two regions, specifically with regards impact of environmental factors (temperature, sunlight), riverine inputs, groundwater, lateral fluxe...

High-resolution records of the past 2000 yr are compared in a north–south transect (28° N to 24° N) of three cores from the eastern slopes of the Guaymas, Carmen, and Pescadero Basins of the Gulf of California (hereafter referred to as the “Gulf”). Evenly-spaced samples from the varved sediments in each core allow sample resolution ranging from ∼ 16 to ∼ 37 yr. Diatoms and silicoflagellates cap...

From October 1996 through September 1998, we used bottom-mounted hydrophone arrays to monitor deep-water areas north and west of the British Isles for songs of humpback whales (Megupteru novaeangliae). Singing humpbacks were consistently detected between October and March from the Shetland-Faroe Islands south to waters west of the English Channel. Temporal and geographic patterns of song detect...

The southwestern tropical Pacific, part of a major pathway for waters feeding the Equatorial Undercurrent, is a region of important geochemical enrichment through land-ocean boundary exchange. Here we develop an original method based on the coupling between dynamical modeling and geochemical tracer data to identify regions of enrichment along the water pathways from the subtropics to the equato...

Pseudambasia appears to be an Indo-West Pacific endemic, comprising mostly tropical and temperate species but also one from the New Zealand subantarctic. In this paper the genus Pseudambasia Stephensen is diagnosed against all other genera of the Lysianassinae. Six new species of Pseudambasia (P. dartnalli sp. nov.; P. lochi sp. nov.; P. ponderi sp. nov.; P. poorei sp. nov.; P. sheardi sp. nov....
