Bluelink is Australia's contribution to the Global Ocean Data Assimilation Experiment (GODAE). The goals of GODAE include the development and application of eddy-resolving, data assimilating ocean forecast systems. In this paper, we describe several aspects of the Bluelink effort that are motivated by this goal. One of the main innovations of Bluelink is(More)
[1] We perform a series of Observing System Experiments (OSEs), where components of the Global Ocean Observing System (GOOS) are systematically withheld from a data assimilating ocean reanalysis. We assess the relative importance of Argo temperature (T) and salinity (S) profiles, sea-surface temperature (SST) and altimetric sea-level anomalies (SLA) for(More)
The Bureau of Meteorology is scheduled in 2007 to expand its oceanographic services for the Australian community to include operational mesoscale ocean forecasts. The past decade has seen the rapid development of a near real-time global ocean observing system which includes both in-situ and satellite instrumentation. The spatial coverage and frequency of(More)
The generation and evolution of eddies in the ocean are largely due to instabilities that are unpredictable, even on short timescales. As a result, eddy-resolving ocean reanalyses typically use data assimilation to regularly adjust the model state. In this study, we present results from a second-generation eddy-resolving ocean reanalysis that is shown to(More)
A series of observing system simulation experiments (OSSEs) are performed for the tropical Indian Ocean (Ϯ15° from the equator) using a simple analysis system. The analysis system projects an array of observations onto the dominant empirical orthogonal functions (EOFs) derived from an intermediate-resolution (2° ϫ 0.5°) ocean circulation model. This system(More)
The Bluelink Ocean data assimilation system (BODAS) is an ensemble-based system that underpins Australia's operational short-range ocean forecast system. The primary test-bed for the Bluelink system is the series of Bluelink ReANalysis (BRAN) experiments. Over the life of Bluelink, BRAN experiments have been used to assess the performance of the system, and(More)
Synopsis 1 The marine environment plays an increasingly important role in shaping 2 economies and infrastructures and touches upon many aspects of our lives, 3 including food supplies, energy resources, national security and recreational 4 activities. GODAE and GODAE OceanView have provided platforms for 5 international collaboration which significantly(More)
