Abstract

Maritime historical documentary sources of weather and state of sea surface including sea ice can aid in filling a known climate knowledge gap for the Southern Ocean and Antarctica for the first half of the 20th century. This study presents a data set of marine climate, sea ice and icebergs recovered from a collection of logbooks from mainly Norwegian whaling factory ships that operated in the Southern Ocean during 1929–1940. The data set comprises some 8000 weather and 4000 sea ice/open sea records from austral summers of the study period. This paper further discusses the structure and content of most common Norwegian maritime documentary sources of the period along with the practices of logging information relevant for the study, such as time keeping, positioning and making weather observations. An emphasis was made on recovery of notes on sea ice and icebergs and their interpretation in terms of WMO categories of sea ice concentration. Data, including ship‐related metadata from all individual documents are homogenized and structured to a common machine‐readable format that simplifies its ingestion into relevant climate data depositories.

1929 年至 1940 年期间南大洋海冰、冰山和海上来源的气象数据

有关包括海冰在内的天气和海面状况的海洋历史文献资料有助于填补 20 世纪上半叶南大洋和南极洲已知气候知识的空白。本研究介绍了一套海洋气候、海冰和冰山数据集，该数据集是从 1929-1940 年期间在南大洋作业的挪威捕鲸船的航海日志中收集的。数据集包括研究期间澳大利亚夏季的约 8000 条天气记录和 4000 条海冰/公海记录。本文进一步讨论了这一时期最常见的挪威航海文献资料的结构和内容，以及与研究相关的信息记录做法，如计时、定位和天气观测。重点是恢复有关海冰和冰山的记录，并根据世界气象组织的海冰浓度类别对其进行解释。所有单个文件中的数据，包括与船舶有关的元数据，都经过了统一处理，并以通用的机器可读格式进行了结构化，从而简化了将其输入相关气候数据存储库的工作。

期刊介绍： Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
