This article reviews the discovery, development, and use of high-frequency (HF) radio wave
backscatter in oceanography. HF radars, as the instruments are commonly called, remotely …

This article reviews the past 15 years of developments in regional ocean data assimilation. A
variety of scientific, management, and safety-related objectives motivate marine scientists to …

The Last Millennium Reanalysis (LMR) utilizes an ensemble methodology to assimilate
paleoclimate data for the production of annually resolved climate field reconstructions of the …

An “offline” approach to DA is used, where static ensemble samples are drawn from existing
CMIP climate‐model simulations to serve as the prior estimate of climate variables. We use …

This paper addresses the structure and dynamical mechanisms of regional and mesoscale
physical variability in the subtropical northeast Pacific Ocean using the Regional Oceanic …

Abstract The Southern Annular Mode (SAM) is the leading mode of atmospheric variability in
the extratropical Southern Hemisphere and has wide ranging effects on ecosystems and …

Abstract The western North Pacific anomalous anticyclone (WNPAC) is an important low-
level circulation system that connects El Niño and the East Asian monsoon. In this study, the …

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 …

This paper summarizes recent efforts on Observing System Evaluation (OS-Eval) by the
Ocean Data Assimilation and Prediction (ODAP) communities such as GODAE OceanView …

Ocean data assimilation is increasingly recognized as crucial for the accuracy of real-time
ocean prediction systems and historical re-analyses. The current status of ocean data …
