IMOS - ACORN - Newcastle HF ocean radar site (New South Wales, Australia) - Delayed mode sea water velocity

The Newcastle (NEWC) HF ocean radar system covers an area of the Central Coast, New South Wales, an area subject to the variability of the East Australian Current (EAC) and its coupling with coastal winds, tides, and waves. In this area the EAC separates from the coast and generates several eddies which control the larval species and the higher marine species and ecosystems in which they forage.

The NEWC HF ocean radar system consists of two SeaSonde crossed loop direction finding stations located at Sea Rocks (32.441575 S 152.539022 E) and Red Head (33.010245 S 151.727059 E). These radars operate at a frequency of 5.2625 MHz, with a bandwidth of 25 KHz, a maximum range of 200 Km and a range resolution of 6 Km. Within the HF radar coverage area surface currents are measured.

纽卡斯尔（NEWC）高频（HF）海洋雷达系统的覆盖范围为新南威尔士州中部海岸区域，该区域受东澳洋流（East Australian Current, EAC）的变化及其与近岸风、潮汐和海浪的耦合作用影响。在此区域内，东澳洋流会脱离岸线并形成若干涡旋，这些涡旋会调控幼体物种及其赖以觅食的高等海洋物种与相关生态系统。
纽卡斯尔高频海洋雷达系统由两套SeaSonde交叉环测向站组成，分别部署于海岩站（坐标：南纬32.441575°，东经152.539022°）和雷德黑德站（坐标：南纬33.010245°，东经151.727059°）。该雷达系统工作频率为5.2625 MHz，带宽25 kHz，最大探测距离达200千米，距离分辨率为6千米。在该高频雷达的覆盖区域内，可实现表层海流的观测。
