Semi-automated open water iceberg detection from Landsat applied to Disko Bay, West Greenland [PDF]

open access: yesJournal of Glaciology, 2019
Changes in Greenland's marine-terminating outlet glaciers have led to changes in the flux of icebergs into Greenland's coastal waters, yet icebergs remain a relatively understudied component of the ice-ocean system.

Multi-cohort machine learning identifies predictors of cognitive impairment in Parkinson’s disease [PDF]

open access: yesnpj Digital Medicine
Cognitive impairment is a frequent complication of Parkinson’s disease (PD), affecting up to half of newly diagnosed patients. To improve early detection and risk assessment, we developed machine learning models using clinical data from three independent

CME iceberg order detection and prediction [PDF]

open access: yesQuantitative Finance, 2020
We propose a method for detection and prediction of native and synthetic iceberg orders on Chicago Mercantile Exchange. Native (managed by the exchange) icebergs are detected using discrepancies between the resting volume of an order and the actual trade size as indicated by trade summary messages, as well as by tracking order modifications that follow

Surveying Drifting Icebergs and Ice Islands: Deterioration Detection and Mass Estimation with Aerial Photogrammetry and Laser Scanning

open access: yesRemote Sensing, 2018
Icebergs and ice islands (large, tabular icebergs) are challenging targets to survey due to their size, mobility, remote locations, and potentially difficult environmental conditions.

Towards automatic extraction of expressive elements from motion pictures : tempo [PDF]

open access: yes, 2000
This paper proposes a unique computational approach to extraction of expressive elements of motion pictures for deriving high level semantics of stories portrayed, thus enabling better video annotation and interpretation systems. This approach, motivated

Line-of-sight iceberg edge-following using an AUV equipped with multibeam sonar [PDF]

open access: yes, 2015
Obtaining 3D information about ice features, like icebergs, are of interest to researchers and offshore operators moving into the Arctic. Icebergs are affected by wind, and ocean currents, and can have unpredictable drift patterns, causing challenges ...

Selection of the key earth observation sensors and platforms focusing on applications for Polar Regions in the scope of Copernicus system 2020-2030 [PDF]

open access: yes, 2019
An optimal payload selection conducted in the frame of the H2020 ONION project (id 687490) is presented based on the ability to cover the observation needs of the Copernicus system in the time period 2020–2030.

Automatic Detection of Small Icebergs in Fast Ice Using Satellite Wide-Swath SAR Images

open access: yesRemote Sensing, 2019
Automatic detection of icebergs in satellite images is regarded a useful tool to provide information necessary for safety in Arctic shipping or operations over large ocean areas in near-real time.

Optimization results for a generalized coupon collector problem [PDF]

open access: yes, 2015
We study in this paper a generalized coupon collector problem, which consists in analyzing the time needed to collect a given number of distinct coupons that are drawn from a set of coupons with an arbitrary probability distribution.

Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstruction [PDF]

open access: yesThe Cryosphere
Tabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, contributing freshwater and nutrients to the ocean ...
