В данной статье анализируются результаты океанографических съемок, выполненных в Ис-фьорде, включая заливы Билле-фьорд и Грён-фьорд, в летние месяцы с 2011 по 2017 г. Основная цель статьи — описание современного состояния вод Ис-фьорда и его заливов. В первой части статьи анализируются особенности распределения водных масс в Ис-фьорде и Билле-фьорде в летние месяцы с 2014 по 2017 г. и в Грён-фьорде в летние месяцы с 2011 по 2017 г. Анализ измерений показал, что для Ис-фьорда и Грён-фьорда было характерно наличие четырех водных масс: поверхностной, промежуточной, трансформированной атлантической и атлантической. В июне 2014 г. была зафиксирована ситуация, когда вся акватория Ис-фьорда и Грён-фьорда была занята атлантическими водами. Для Билле-фьорда было характерно также наличие четырех водных масс: поверхностной, промежуточной, локальной и зимней. В 2016 г. был зафиксирован новый исторический максимум температуры в слое атлантических вод в Исфьорде (6,8 °С), что почти на 0,5 °С выше предыдущего рекорда, наблюдавшегося в 2006 г. Также по результатам расчетов для 2016 г. были получены максимальные средние значения температуры воды, теплосодержания в верхнем 40-метровом слое в Ис-фьорде, Билле-фьорде и Грён-фьорде, в целом 2016 г. стал самым теплым для этих заливов за исследуемый период.

The study is based on CTD measurements collected during Arctic cruises in Isfjorden including Billefjorden and Gronfjorden in summer between 2011 and 2017. The purpose of this paper is to describe the present state of fjords water masses. In the first part of the paper distributions of water masses in Isfjorden and Billefjorden in summer 2014–2017 and in Grönfjorden in summer 2011– 2017 are analyzed. In paper was shown that for Isfjorden and Grönfjorden there were 4 types of masses: surface water, intermediate water, transformed Atlantic water, and Atlantic water. In June 2014, was recorded the situation when Atlantic waters occupied the entire water area of Isfjord and Grönfjord. In summer in Billefjorden were identified 4 types of masses: surface water, intermediate water, local water, and winter water. In Isfjorden, new maximum temperature of Atlantic water was observed (6.85 °С) in summer 2016. It is greater on almost 0.5 °С than previous warmest peak in 2006. The maximum average values of water temperature, heat content in the upper 40 m layer were recorded in 2016. The summer 2016 was the warmest in Isfjorden, Billefjorden and Grönfjorden during the survey period.
