陸地這一側
最直接的一支：把海岸線當成位置的分界，東西就擺在陸地那一邊。
adjective · B2
Happening or placed on the land rather than out in the sea. It is used most about work such as drilling for oil and gas, wind farms, and the bases on land that supply them.
陸上的
核心畫面
Picture the coastline as one long line: sea on one side, land on the other. `Onshore` always points at the land side of that line. Sometimes the line is a real beach — an onshore well, an onshore wind, a storm coming onshore. Sometimes the line is the edge of your own country, and then keeping work or money onshore means keeping it at home. Whichever line it is, the word puts you on the land side of it.

可以把海岸線想成一條長長的線。一邊是海，一邊是陸地。onshore 講的永遠是「陸地那一邊」。有時候那條線是真的沙灘：陸上的油井、吹上岸的風、登陸的颱風。有時候那條線是自己國家的邊界：把錢和工作留在線內，就是 onshore。不管是哪條線，這個字都把你放在陸地那一側。From the word’s history
The Wiktionary entry in this packet records the word simply as on + shore.
本批資料的 Wiktionary 條目只寫了一句：onshore 來自 on 加 shore。這正好就是它的核心畫面——「在岸上／朝岸上」。

越線往陸地移動
同一條線，但加上了動作：不是「在哪裡」，而是「往哪裡去」。
adjective · B2
An onshore wind or breeze blows from the sea towards the land.
由海吹向陸地的
國界之內
這一支把那條線換成國界：可以想成整個國家是一座島，海岸線就是法律和稅制的邊。這是一種理解方式，不是在說歷史上一定這樣演變。

Inside your own country rather than abroad. It is used about money, accounts, jobs, data and companies that stay under your country's own laws.
