Selective fishing can disrupt the delicate balance between corals and algae in embattled Caribbean coral reefs. Removing large parrotfish, which graze on algae the way large land mammals graze on gras...
Large marine protected areas effectively protect reef shark populations,Stanford scientists find
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...
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...
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...
Nutrient dynamics and biological consumption in a large continental shelf system under the influence of both a river plume and coastal upwelling
Nutrient dynamics biological consumption large continental shelf system influence of both a river plume coastal upwelling
2014/4/4
We examined the dynamics of dissolved inorganic nitrogen (DIN, nitrate + nitrite), dissolved inorganic phosphorus (DIP), and silicate (Si(OH)4) in the northern shelf of the South China Sea in summer, ...

Experimental evidence of a low-oxygen refuge for large zooplankton
Experimental evidence a low-oxygen refuge large zooplankton
2014/4/4
We tested the hypothesis that hypoxic zones in the metalimnion and hypolimnion of lakes can provide a refuge against fish predation for large zooplankton. Experiments were run in a large indoor mesoco...
Effects of phytoplankton community on production, size and export of large aggregates: A world-ocean analysis
phytoplankton community production, size export of large aggregates: A world-ocean
2014/4/17
We recorded vertical profiles of size distributions of large particles (.100mm) to a 1000-m depth in the Atlantic, Indian, and Pacific Oceans and in the Mediterranean Sea with theUnderwater Video Prof...
Effect of a flood event on the dynamics of phytoplankton and biogeochemistry in a large temperate Australian lagoon

2014/4/17
In episodically driven estuaries, nutrient delivery is typically confined to sporadic flow events, followed by intense biogeochemical recycling of nutrients. We document the response of a temperate la...

2009/4/30
The potential for an outbreak of the phenomenon called "red tide" is expected to be moderately large this spring and summer in the Gulf of Maine, according to researchers at the Woods Hole Oceanograph...
In situ photobiology of corals over large depth ranges: A multivariate analysis on the roles of environment, host, and algal symbiont
In situ photobiology of corals over large depth ranges A multivariate analysis on the roles of environment host algal symbiont
2014/4/21
We applied a multivariate analysis to investigate the roles of host and symbiont on the in situ physiological response of genus Madracis holobionts towards light. Across a large depth gradient (5-40 m...
