Long-term and large-scale modeling of mega-nourishments [PDF]

open access: yes, 2016
The Sand Engine, ZM (Zandmotor), is a hook-shaped mega-nourishment (21.5 millions m³) located on the Dutch coast with an alongshore length of 2.4 km and an offshore extension of 1 km.

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

open access: yesBoreas, EarlyView.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Vortices over bathymetry

open access: yesJournal of Fluid Mechanics
There are numerous examples of long-lived, surface-intensified anticyclones over submarine depressions and troughs in the ocean. These often co-exist with a large-scale cyclonic circulation. The latter is predicted by existing barotropic theory but the anticyclone is not.

Olympic Coast National Marine Sanctuary Habitat Mapping: Survey report and classification of side scan sonar data from surveys HMPR-114-2004-02 and HMPR-116-2005-01. [PDF]

open access: yes, 2006
The Olympic Coast National Marine Sanctuary (OCNMS) continues to invest significant resources into seafloor mapping activities along Washington’s outer coast (Intelmann and Cochrane 2006; Intelmann et al. 2006; Intelmann 2006).

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

open access: yesBoreas, EarlyView.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Effects of Irregular Bathymetry on the Performance and Wake Characteristics of Tidal Stream Turbines: A Case Study of a Tidal Power Site

open access: yes한국해양공학회지
Tidal energy has emerged as a promising renewable energy source, with abundant marine resources available in many parts of the world. To exploit this resource efficiently, reliable and computationally efficient methods are required to analyze energy ...

Bathymetry of Lake Bogoria, Kenya

open access: yesJournal of East African Natural History, 2003
This paper presents the first bathymetric map for the approximately 17 km by 2 km alkaline Lake Bogoria situated in the eastern Rift Valley of Kenya. Longitudinal and transverse cross sections of the lake are also provided. Northern, central and southern basins of the lake had maximum depths of 5.9 m, 10.2 m and 8.4 m respectively.

Shoreline and deglaciation chronology in southeast Norway

open access: yesBoreas, EarlyView.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.
