Marine in situ data collected from sail training ship Statsraad Lehmkuhl in the North and South Atlantic Ocean from 2021-11-25 to 2022-02-23

In August 2021, the 107-year-old 98-meter-long tall ship Statsraad Lehmkuhl departed Norway to return in April 2023, having sailed 55,000 nautical miles and visited 36 ports worldwide. The main goal is to create attention and share knowledge about the crucial role of the ocean for a sustainable development in a global perspective. This dataset contains various marine observations collected in the Atlantic Ocean. This dataset is U.S. State Department MSR U2021-017 as part of the World Data Services for Oceanography. CTD is in TXT and RSK (RBR CTD) formats, navigation is in CSV, PCO2 data are in TXT format, wave radar data are in Python Pickle File (PKL) format, weather station and Ferrybox (through-flow system) data are in JSON format, echosounder data are in Simrad EK80 (*.raw) format, hydrophone sound data are in uncompressed wave format (*.wav). The latter two are compressed by gzip.

2021年8月，拥有107年历史、总长98米的高桅帆船Statsraad Lehmkuhl从挪威启航，于2023年4月完成返航，全程航行55000海里，造访全球36个港口。本次航行的核心宗旨为引发公众对海洋的关注，并从全球视角分享海洋对于可持续发展的关键作用相关知识。本数据集收录了大西洋海域采集的各类海洋观测数据。本数据集隶属于美国国务院MSR U2021-017项目，是世界海洋学数据服务（World Data Services for Oceanography）的组成部分。其中，温盐深仪（CTD）数据采用TXT及RSK（RBR CTD）格式存储，导航数据格式为CSV，二氧化碳分压（PCO₂）数据采用TXT格式，海浪雷达数据存储为Python Pickle文件（PKL）格式，气象站与Ferrybox（通流系统）数据采用JSON格式，回声测深仪数据采用Simrad EK80（*.raw）格式，水听器声学数据采用未压缩波形格式（*.wav）。后两类数据均通过gzip完成压缩。
