Indonesian Seas Finestructure Variability

Intraseasonal Variability in the Indo–Pacific Throughflow and the Regions Surrounding the Indonesian Seas

Intraseasonal oscillations in sea level, sea surface temperature, and upper ocean flow field have recently been observed in various locations surrounding the Indonesian seas. While the observed oscillations at these locations have similar wave periods ranging from 30 to 85 days, their forcing mechanisms can involve different dynamic processes. In order to clarify the dynamic processes essential...

Interannual variability in Nordic seas primary production

Phytoplankton represents the primary trophic level in marine pelagic ecosystems, through which most biological material produced by photosynthesis is further channelled through the foodweb via grazing by zooplankton. Therefore, the level and variability of primary production is believed to be an important factor for fish recruitment and growth. The Nordic seas are important feeding areas for la...

Simulated and Observed Circulation in the Indonesian Seas: 1/12° Global HYCOM and the INSTANT Observations

Observed strengthening of interbasin exchange via the Indonesian seas due to rainfall intensification

A proxy of the Indonesian Throughflow (ITF) transport, developed using in situ hydrographic measurements along with assimilations, shows a significant strengthening trend during the past decade. This trend is due to a freshening and subsequent increase in the halosteric component of the ITF transport associated with enhanced rainfall over the Maritime Continent over the same period. The strengt...

Pathways of Intraseasonal Variability in the Indonesian Throughflow Region

The recent INSTANT measurements in the Indonesian archipelago revealed a broad spectrum of time scales that influence Throughflow variability, from intraseasonal (20-90 days) to interannual. The different time scales are visible in all transport and property fluxes and are the result of remote forcing by both the Pacific and Indian Ocean winds, and local forcing generated within the regional In...
