Scientists Large-Scale Surface Melting Event Antarctica 2015-16 El Nino
2017/7/21
The West Antarctic Ice Sheet, a landbound mass of ice larger than Mexico, experienced substantial surface melt through the austral summer of 2015-2016 during one of the largest El Niño events of ...

Large marine protected areas reef shark populations Stanford scientists
2017/2/16
Originating 423 million years ago, sharks are a group of predators that span 490 species and still play crucial roles within their ecosystems. We often characterize these top predators as nearly indes...
Study Shows Large Variability in Abundance of Viruses that Infect Ocean Microorganisms
Large Variability Viruses Infect Ocean Microorganisms
2016/2/22
Collecting and re-examining more than 5,600 estimates of ocean microbial cell and virus populations recorded over the past 25 years, researchers have found that viral populations vary dramatically fro...
Operational Observation Networks for Ports, a Large Estuary and an Open Shelf
Open Shelf Ports
2015/8/5
This paper describes the goals, capabilities and accomplishments of three operational coastal ocean observation networks. In the companion paper in this volume, the authors discuss reasons for the rap...
Large Igneous Provinces and Scientific Ocean Drilling:Status Quo and A Look Ahead
Large Igneous Provinces Scientific Ocean Drilling Status Quo Look Ahead
2015/7/24
A rich mosaic of disparate crustal types characterizes the Earth beneath the sea. Although "normal" oceanic crust approximately 7-km thick is by far the most prevalent, abnormally thick oceanic-type c...
Signature of Large Aspect Ratio Roll Vortices in Synthetic Aperture Radar Images of Tropical Cyclones
Large Aspect Ratio Roll Vortices Synthetic Aperture Radar Images Tropical Cyclones
2015/7/16
Synthetic aperture radar images of tropical cyclones have been processed into high-resolution surface wind vector fields. Examination of the surface wind divergence and wind stress curl show that wind...
A New Database to Explore the Findings from Large-Scale Ocean Iron Enrichment Experiments
New Database Large-Scale Ocean Iron Enrichment Experiments
2015/7/15
Some of the largest scientific manipulation experiments conducted on our planet have enriched broad swaths of the surface ocean with iron. Surface ocean signatures of these iron enrichment experiments...
Estimates of the number of seamounts occurring worldwide are high and increasing, largely because of improved remote-sensing capabilities. Numbers have grown from a baseline of 15,000 (Wessel, 2001; M...
The variability of the large-amplitude internal wave field on the Australian North West Shelf
Internal waves Solitary waves Internal tide Continental slope Australian North West Shelf (14–221S, 114–1261E)
2015/6/30
Observations are presented of large-amplitude internal waves (LAIWs) generated by the steepening of the internal tide on the Australian North West Shelf (NWS) over a 4-month period extending from stro...
Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
Large-scale geographical variation in prokaryotic abundance and production in meso- and bathypelagic zones of the central Pacific and Southern Ocean
Large-scale geographical variation prokaryotic abundance production meso- and bathypelagic zones central Pacific Southern Ocean
2014/4/2
Heterotrophic production and abundance of prokaryotes (i.e.,BacteriaandArchaea) in meso- (200–1000 m) and bathypelagic (.1000 m) zones were measured at 31 stations along meridional transects of the ce...
