Anthropogenic activity has a negative impact on many coastal ecosystems, compromising the significant direct and indirect socio-economic benefits provided in these areas. Maintaining activities that depend on coastal zones while preserving the ecological state of the ecosystems represents a management challenge. Management of coastal zones requires scientifically based knowledge, due to the com...
The coastal marine environment of Japan is characterized by its high biological productivity, which contributes to generally high fishery yields. However, both the productivity of coastal ecosystems and coastal fisheries are being threatened by substantial changes in the coastal marine environment. This situation is making it increasingly imperative to take an ecosystems approach to management ...
Coastal environmental monitoring has become an important technique for scientific research and integrated management of coastal zone, which could produce a large number of long-term, fixed-point, continuous, large-scale, multi-factor monitoring data from space, air, sea surface, underwater, to seabed and etc. In this paper, the framework of the coastal environmental monitoring data integration ...
Coastal areas play a crucial role in the economical, social and political development of most countries; they support diverse and productive coastal ecosystems that provide valuable goods and services. Globally flooding and coastal erosion represent serious threats along many coastlines, and will become more serious as a consequence of human-induced changes and accelerated sea-level rise. Over ...
We thank Yang et al. (1) for their perspective. We are aware of the importance of coastal wetland protection for endangered migratory birds. Our paper in PNAS (2) focuses on the general representation of protected areas for endangered species (e.g., endangered birds) and ecosystem services. Thus, we did not emphasize the representation in nature reserves of coastal wetlands for endangered migra...
Astyanax douradilho, new species, is described from the rio Tramandaí system, coastal drainage of Rio Grande do Sul State, Brazil. The new species is distinguished from its congeners by possessing 37-39 perforated scales along the lateral line, 3-5 maxillary tricuspid teeth, 22-24 branched anal-fin rays, absence of a conspicuous dark stripe from humeral region to caudal peduncle, two vertically...
We observed vertically displaced coastal and river markers after the 27 February 2010 Chilean earthquake [moment magnitude (Mw) 8.8]. Land-level changes range between 2.5 and -1 meters, evident along an approximately 500-kilometers-long segment identified here as the maximum length of coseismic rupture. A hinge line located 120 kilometers from the trench separates uplifted areas, to the west, f...
[1] Analysis of new data for eight stations in coastal southern Greenland, 1958–2001, shows a significant cooling (trend-line change 1.29 C for the 44 years), as do sea-surface temperatures in the adjacent part of the Labrador Sea, in contrast to global warming (+0.53 C over the same period). The land and sea temperature series follow similar patterns and are strongly correlated but with no obv...
As mapping products become increasingly digital and require rapid updating, it is necessary for survey companies to use fast and cost-effective technologies. Airborne laser mapping provides a new alternative for traditional photogrammetric mapping. Based on a scanning laser and GPS/Inertial positioning system, an airborne laser system automatically produces accurate digital elevation models (DE...
Th is paper reports research on service branding carried out on the prestigious Norwegian Coastal Voyage, or Hurtigruten, which is its brand name. Th e primary research instrument employed in the research was semi-structured in-depth interviews with managers and service personnel previously and presently employed by the shipping line Hurtigruten ASA. Th e paper shows that a set of factors infl ...
