「舊金山潮位站」探訪

A Visit to San Francisco Tide Station

「舊金山潮位站」位於美國加州舊金山灣，由美國「國家海洋及大氣總署」(NOAA,National Oceanic and Atmospheric Administration)經營管理。本站創立於1854年，是一個具有長久歷史的潮位站。初始以「浮筒式」自記潮位計為觀測工具，目前則使用雷達式與壓力式潮位計。除水位觀測外，本站亦有多種氣象觀測儀器，並觀測水溫與導電度。本文記載2023年6月探訪「舊金山潮位站」的所見，並由網際蒐尋與個人聯繫所獲得之相關資訊，彙整介紹該潮位站與其周邊水準點之現狀與功能。

The 'San Francisco Tide Station' is situated in the San Francisco Bay, California, USA, and is managed by the National Oceanic and Atmospheric Administration (NOAA). Established in 1854, this station boasts a rich history of operation. In its early days, the station utilized a 'float' type tide gauge, but it has since transitioned to RADAR and pressure gauges as the primary observation measures. In addition to monitoring water levels, the station also collects meteorological data, water temperature, and water conductivity. This document presents the findings from an on-site visit conducted in June 2023, supplemented with information obtained from NOAA and gathered from the Internet. The aim is to provide a comprehensive overview of this tide station and the surrounding benchmarks.
