Brooklyn Aquarium now growing beautiful coral

"Growing corals... preserve these fragile eco systems while educating the public about coral reefs in the wild," said WCS Vice President and New York Aquarium director Jon Forrest Dohlin.

Due to disturbances like climate change and unchecked coastal development nearly one-third of the world’s coral reefs have been lost. Some estimates predict corals will be extinct by 2050. So, the aquarium is growing its own.

Blue marlins and many other billfish are high-energy fish that need large amounts of dissolved oxygen.

Expanding ocean dead zones are shrinking marlin habitat

Dead zones are areas in the ocean where oxygen levels are so low that most fish cannot survive over the long term.

Blue marlins and many other billfish are high-energy fish that need large amounts of dissolved oxygen. By comparing the movement of the blue marlins and the location of low-oxygen areas, scientists have shown that blue marlins venture deeper when dissolved oxygen levels are higher, and remain in shallower surface waters when low dissolved oxygen areas encroach on their habitat from below.

Geo-targetting is a technique whereby different version of banner ads can be served to different audiences while just occupying one slot

Geo-targeting is included. But what is it?


The most obvious use of the geo-targeting option is to have different versions of your ad presented in various languages, as mentioned in the introduction above. The banner ad serving software can even differentiate between, say, French-speaking and English-speaking Canadians; and in the US, the geographic resolution can be broken down to city level. Even if you only have one language or version of the ad, you can still make good use of this feature, say, if you have regional distributors to whom you want to direct local inquiries.

Rebreather owners needed

The aim is to evaluate use of existing carbon dioxide (CO2) canister tracking technology within the recreation and technical diving community.

Survey results will be published to the scientific literature as soon as they are compiled with preliminary results presented at Rebreather Forum 3.0 in May 2012

A new article provide a unique view of the ecology of early life stages of sphyraenids (great barracuda and the closely related sennets)

What baby Barracudas are up to

In the journal Marine Biology, lead author Dr. Evan D’Alessandro and University of Miami Rosenstiel School of Marine & Atmospheric Science colleagues Drs. Su Sponaugle, Joel Llopiz and Robert Cowen shed light on the larval stage of this ocean predator, as well as several other closely related species.
