Restoration of data on water temperature in the Kola Section for 2016–2017
Abstract
The Kola Section is mainly located in the southern part of the Barents Sea and crosses the Atlantic waters flowing from the Norwegian Sea into the Barents Sea and further into the Arctic Basin. Observations along the section started in May 1900 and it is one of the world’s longest time-series. Unfortunately, in 2016 and 2017, the Kola Section was not occupied during 12 months (from June 2016 to May 2017 inclusive); this unique time-series was interrupted. This paper presents methods and results of restoration of missed data on water temperature in the Kola Section in 2016–2017. The restoration was carried out using: (1) internal structure of data series from the Kola Section, (2) multiple linear regression method and data from other nearby sections, namely: «Fugløya–Bjørnøya» and «Vardø-N», (3) modelled data from the Copernicus website. As a result, data on water temperature in the 0–50, 0–200, 50–200 and 150–200 m layers in the inner (stations 1–3), central (stations 3–7) and outer (stations 8–10) parts of the Kola Section were restored for each month from June 2016 to May 2017.
