Study links powerful waves in Kara Gate Strait to tides
Researchers studying the Kara Gate Strait, between Russia’s Barents and Kara seas, linked powerful internal waves there to tides and currents.
Internal waves move through layers of water with different densities, even when the sea surface looks calm.
In measurements taken during an expedition in July 2023, the team recorded more than 30 wave-like movements over eight hours, some shifting water layers by nearly 30 metres.
The researchers identified three formation mechanisms; the study describes waves formed as currents pass over underwater hills and waves produced when an internal tide changes shape.
Which mechanism dominates can vary during the tidal cycle.
When internal waves break, they help mix water and move heat and nutrients between deeper and surface layers.
The findings help explain why waves appear in different parts of the strait and travel in different directions.
A research team linked powerful internal waves in the Kara Gate Strait to tidal currents and the strait’s underwater terrain.
The waves can shift water layers vertically by almost 30 meters.
Measurements during an expedition in July 2023 recorded more than 30 wave-like movements over eight hours.
The researchers identified three mechanisms that can produce the waves, although the source article does not describe the third mechanism.
The strait lies between Novaya Zemlya and Vaygach Island, between the Barents and Kara seas.
- Who
- A research team from two Russian Academy of Sciences institutes and the Moscow Institute of Physics and Technology.
- What
- The team linked powerful internal waves in the Kara Gate Strait to tides and identified three formation mechanisms.
- When
- Measurements were taken in July 2023. The study was reported on October 12, 2026.
- Where
- The Kara Gate Strait, between the Barents and Kara seas.
- Why
- The researchers sought to explain how the waves form, why they appear regularly in different parts of the strait, and how they spread.
This story does not have two clearly opposing sides.
Scientists measured water temperature and salinity at different depths during an expedition aboard the Dalniye Zelentsy research vessel.
The team recorded more than 30 wave-like movements, some reaching almost 30 meters.
TASS reported that the research team had linked the waves to tides and identified three formation mechanisms.
