Australian Shark Attack

A shark attack left one man dead in Australia.  Australia's relatively large number of annual shark attacks led the government to undertake a shark hunt last year, despite the fact that so many shark populations are crashing and that we are the ones invading sharks' "turf" (not vice cersa).

National Geographic Website

I was just exploring a bit more in National Geographic's website, and discovered their page devoted to things going on in the world ocean.  Like everything NatGeo does, it is really well done.

Definitely worth checking out.

Arctic Sea Ice Concentration - 8/17/14

It's hard to believe, but here in NY the beginning of the school year is fast approaching.  Time to end the summer 'blogging hiatus' and get back to work.

This article from Dr. Jeff Masters at Weather Underground caught my eye this morning  The main point of his blog post is that this past July (2014) was recently ranked the 4th and 11th warmest July on record according to NCDC and NASA, respectively.  He provides lots of examples.

So why is this in Chaminade's oceanography blog? Scroll down in his post to where he mentions the Arctic sea ice concentration, along with the status of the Northeast and Northwest Passages.

Gone Fishin'

Paralichthys dentatus (Summer Founder)

Great article here on summer flounder, otherwise known as fluke.  The article also addresses a warming North Atlantic Ocean and fisheries management.  Summer flounder are a nice success story in terms of fisheries management.  After the collapse of stocks in the late 1980s due to overfishing (of course; what else?), NOAA imposed strict quotas.  While those quotas were painful for quite some time, they did allow time for the summer flounder stocks to rebound.  And they've rebounded rather nicely.

Here's a link to a new article posted on Scientific American's webstie regarding the relationship between this potentially strong El Nino and the fire-ravaged areas of the western United States.

Shark Skin

Sharks have been  around for a long long time, about 400+ million years including their most ancient ancestors.  They are amazingly adapted to their environments.

I just read this awesome article on 3D printed shark skin done by a group of researchers at Harvard.  Amazing stuff!

El Nino Coming?

More and more NOAA thinks an El Nino event may be developing.  Click to the linked article from NASA's Earth Observatory.
