The goal of this research has been to determine the nature and origin of low-latitude terrestrial climate variability prior to and after the rapid expansion of high-latitude ice sheets near 2.4 Myr to understand the interactions between high- and low-latitude climate systems sin…

A real time numerical model is developed to simulate tidal flow in the interconnected Musi-Upang estuaries, South Sumatra, Indonesia. The model adopted the existing code for solving two dimensional shallow water wave equations. The code utilized an explicit finite difference sch…
The principal objective of this study is to develop a new method to detect wave motion from satellite altimetric measurements of sea surface height. The essence of the approach is to construct a two-dimensional Fourier series representation of the amplitude field in wavenumber s…
The fishery and the biology of the inshore squid Loligo vulgaris were studied at the artisanal fishery of Tifnit from May 1985 to April 1986. The total landing in the area was 96 tons, with a local sale value of 2,113,510 dirhams. Dories using trammel nets landed 67% of the catc…
In the years 1991 and 1992 combined vertical electric (VES) and electromagnetic (EM) soundings, complemented by chemical analyses of borehole water samples, were made with the ahn of detecting and mapping saline-fresh water interfaces in coastal and estuarine sediments. Two coas…
El conocimiento actual de los patrones de diversidad biológica se basa principalmente en laevaluación de la riqueza de especies a distintas escalas. Es reconocido ampliamente que estamedida de diversidad no se distribuye al azar, donde el patrón más recurrente y documentado aesc…
Colonial encounters between Europeans and Indigenous people have long been an important topic in historical archaeology as scholars seek to explore their effects on Indigenous social, cultural, and material worlds. However, our current understanding heavily relies on studies of …
The main objective of this study is to examine factors that control the Indonesian throughflow and its variability. The study consists of three parts, an inverse analysis of tracer data along the throughflow pathways, analysis of the flow structure in the Makassar Strait, and dy…
The primary objectives of this study were to better understand the remote sensing mechanisms of ocean internal waves, and to apply space shuttle data to studies of upper ocean processes. Space shuttle photographs and Spaceborne Imaging Radar-C images of the Arabian Sea area were…
This study analyzes the heat budget of the Arabian Sea using satellite-derived sea surface temperature (SST) from 1985–1995 and other data sets. To better understand air-sea interaction, canonical average monthly and seasonal fields representing the spatial and temporal structur…
This study investigated the natural phytoplankton assemblage of Ambon Bay, eastern Indonesia, over a two-year period, including the composition of the dominant microplankton and the influence of environmental factors with emphasis on the role of mangrove in Ambon Bay. A hoped-fo…
The survey was conducted along 2,475 kilometers of tract in the South China Sea offshore East Peninsular Malaysia to evaluate the presence of placer gold, tin and heavy minerals, as well as sand resources. Geophysical methods were employed, consisting of high resolution seismic …
The flow of water from the equatorial Pacific Ocean to the Indian Ocean through the Indonesian seas has local, regional and global importance. The Indonesian Throughflow (ITF) is involved in modification of Pacific Ocean water masses, poleward transport of ocean heat, interactio…
The presence of hydrothermal vents on the seafloor at present-day spreading centres, and the lower than expected conductive heat flow values at ridge crests requires the convective circulation of fluids in oceanic crust. The fractured nature of oceanic crustal rocks further sugg…
The red tide dinoflagellate Pyrodinium bahamense Plate var. compressum Bohm is the causative organism responsible for most paralytic shellfish poisoning (PSP) events in the tropical Pacific. Little information is available on the physiology and toxin production characteristics o…
Copepod fecal pellets can be an important vector for transporting organic carbon and amino acids from the surface waters to deep water and the sediments. Understanding the processes, e.g., fecal pellet production, organic carbon composition and concentration along with dissolved…
Trichodesmium spp. are nitrogen fixing marine cyanobacteria that are frequently the most abundant phytoplankton in tropical oligotrophic waters. This study calculated that Trichodesmium supply the Northern Caribbean Sea 4.1\times10\sp9 gN/day via nitrogen fixation, more than any…
Chemical and hydrographic tracer data obtained during the GEOSECS and WOCE expeditions along with historical hydrographic data are used to examine the deep overturning circulation in the Indian Ocean. The mean upwelling transport of bottom water in the Indian Ocean north of 30°S…
