♫NASA 壯觀的全球洋流影片 [永恆的海洋]

Perpetual Ocean by NASA

美國航太總署(NASA)提供一套壯觀的全球海洋「洋流 / 時間遞移」電腦模擬動畫。
(特別看看影片中時段1:10~1:25台灣附近複雜的洋流型態)

影像中顯示從2005年6月到2007年12月期間，全球的海洋表面洋流，
目的是利用海洋流數據來建立一套簡單且內聚的經驗。

影片製作是運用NASA噴射推進實驗室的計算模型來估算被稱為-「第二階段或ECCO2的海洋環流和氣候」

(ECCO2是高解析的全球海洋和海冰模型

ECCO2嘗試模擬出海洋和海冰的模式，並能逐漸正確地解釋海洋渦旋和其他細部海流系統所傳輸的熱量和碳排放問題。

ECCO2模擬所有深度的海洋流動，但只有表面流動出現在此段視訊。

海洋中深色圖案代表海底地形。
海底地形是以20倍呈現，水深則以40倍呈現。

This visualization shows ocean surface currents around the world during the period from June 2005 through Decmeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.

This visualization was produced using NASA/JPL's computational model called Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2.. ECCO2 is high resolution model of the global ocean and sea-ice. ECCO2 attempts to model the oceans and sea ice to increasingly accurate resolutions that begin to resolve ocean eddies and other narrow-current systems which transport heat and carbon in the oceans.The ECCO2 model simulates ocean flows at all depths, but only surface flows are used in this visualization. The dark patterns under the ocean represent the undersea bathymetry. Topographic land exaggeration is 20x and bathymetric exaggeration is 40x.
