In 1842, Darwin identified three types of reefs: fringing reefs, which are directly attached to volcanic islands; barrier reefs, which are separated from volcanic islands by lagoons; and ring reefs, which enclose only a lagoon and are defined as atolls. Moreover, he linked these reef types through an evolutionary model in which an atoll is the logi...
GRASS GIS Modules for Topographic and Geophysical Analysis of the ETOPO1 DEM and Raster Data: North Fiji Basin, Pacific Ocean The paper presents topographic analysis based on the raster data (NetCDF and grid formats) and visualization of the geophysical datasets that resembles the topographic surface. Geographically, the research focuses on the reg...
© 2020, The Author(s). Macroids and rhodoliths, made by encrusting acervulinid foraminifera and coralline algae, are widely recognized as bioengineers providing relatively stable microhabitats and increasing biodiversity for other species. Macroid and rhodolith beds occur in different depositional settings at various localities and bathymetries wor...

The municipality of Bahía Solano possesses important tourist attractions. The majority of them consist of natural wonders such as whale, dolphin and bird watching. Its marine area offers diving courses, all types of fishing, surfing, other water sports etc. The enormous amount of natural wealth stands in contrast to the lack of local development an...

The Cascadia Trench is stretching along the convergent plate boundaries of Pacific Plate, North America Plate and Juan De Fuca Plate. It is an important geomorphological structural feature in the north-east Pacific Ocean. The aim of the paper is to analyse the geomorphology of the Cascadia Trench west of Vancouver Island (Canada and USA) using the ...
A new species of the pontogeneiid amphipod Paramoera shakotanensis from the mouth of Horonaifu River, Hokkaido, Japan, is described. Paramoera shakotanensis sp. nov. can clearly be distinguished from its congeners by a combination of the following features: large eyes, deep antennal sinus without sharp incision, epimeral plate 3 with smooth posteri...

The effects of climate warming on ecosystem dynamics are widespread throughout the world's oceans. In the Northeast Pacific, large-scale climate patterns such as the El Niño/Southern Oscillation and Pacific Decadal Oscillation, and recently unprecedented warm ocean conditions, from 2014-16, referred to as a marine heatwave (MHW), resulted in large-...

Background The intricate geomorphology of the coastline in the Chilean Channels and Fjords region, together with the freshwater inputs from the ice fields provide the area with very unique ecological characteristics and a variety of habitats that favour great marine biodiversity. However, although Chilean Patagonia has been the focus of several exp...

AbstractBased on the data from long sediment cores retrieved by R/V Eltanin (United States) during the 1950s–1960s, Neo- and Eopleistocene lithofacies maps of the southern Pacific Ocean (scale 1 : 20 000 000) and Scotia Sea (scale 1 : 10 000 000) were compiled for the first time. For the Scotia Sea, schemes of isopachites are shown on the respectiv...

AbstractBased on a detailed bathymetric map of the southeastern part of the Magellan Seamounts created using the results of multibeam echo sounding, a lineament analysis of the seafloor relief was performed, linear landforms were distinguished and their azimuths were measured, and a rose diagram was constructed showing the lineament direction in th...
