Experimental and numerical study on ice resistance for icebreaking vessels

International Journal of Naval Architecture and Ocean Engineering, 2015
Ice resistance is defined as the time average of all longitudinal forces due to ice acting on the ship. Estimation of ship’s resistance in ice-covered waters is very important to both designers and shipbuilders since it is closely related to propulsion ...

Monitoring Pacific walrus coastal haulouts by satellite to estimate herd abundance and distribution

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We monitored Pacific walrus haulouts with drone and satellite imagery to derive new methods for estimating minimum population size. The largest herd observed during an 8‐year study period was on the coast of northeastern Russia at Cape Serdtse‐Kamen in autumn 2022 where the aggregation spanned over an area of 184,094 m2 with a mean density (and 90 ...

Seismic Insight on Basement Structure of the Extinct Mid‐Oceanic Ridge in Canada Basin, Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The most accepted theory for the formation of the Canada Basin is that it was created during 66° rotation of Arctic Alaska around the Euler pole located near the Mackenzie Delta sometime during the Mesozoic. Gravity and magnetic anomaly data are consistent with an extinct mid‐oceanic ridge (MOR) in the central basin.

UUV-Assisted Icebreaking Application in Polar Environments Using GA-SPSO

Journal of Marine Science and Engineering
This paper addresses the challenges faced by icebreakers in polar environments, particularly the difficulty in sensing underwater ice formations when navigating through thick ice layers, which often results in suboptimal icebreaking effectiveness.

The essential role of large research vessels in marine ecosystem observations and ocean sustainability

Limnology and Oceanography, Volume 70, Issue 9, Page 2767-2792, September 2025.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.

Prediction of ship resistance in level ice based on empirical approach

International Journal of Naval Architecture and Ocean Engineering, 2017
A semi-empirical model to predict ship resistance in level ice based on Lindqvist's model is presented. This model assumes that contact between the ship and the ice is a case of symmetrical collision, and two contact cases are considered.

Mother Tongue Influence and Global English: Creating “Neutral” Elites in Delhi's Business Processing Outsourcing Industry

American Anthropologist, Volume 127, Issue 3, Page 466-475, September 2025.
ABSTRACT Mother tongue influence (MTI) is a widely used yet often underdefined term in India's business process outsourcing (BPO) industry. “Mother tongue” is an unavoidable, yet fraught political category linked to sovereignty, education, region, and ethnicity.
