  • Optical properties of the Antarctic system and new radiation information

    20 Nov 2009 | 8:00 pm
    In a new study, measurements were made during three Austral summers to study the optical properties of the Antarctic system and to produce radiation information for additional modeling studies. The system has an important part in the global climate due to its size, its high latitude location and the negative radiation balance of its large ice sheets.

  • Paleontologists find extinction rates higher in open-ocean settings during mass extinctions

    19 Nov 2009 | 11:00 pm
    Researchers have uncovered a strikingly pattern for ancient mass extinctions: extinctions rates during mass extinctions were significantly higher in open-ocean-facing settings than in epicontinental seas, indicating that open-ocean settings were more susceptible to the mass-extinction-causing agents.

  • Oceans' uptake of human-made carbon may be slowing

    19 Nov 2009 | 5:00 am
    The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions -- a finding with potentially wide implications for future climate.

    A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day.

  • Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis (update)

    Anne-Marin Nisumaa
    16 Nov 2009 | 6:35 am
    Cephalopods play a key role in many marine trophic networks and constitute alternative fisheries resources, especially given the ongoing decline in finfish stocks. Along the European coast, the eggs of the cuttlefish Sepia officinalis are characterized by an increasing permeability of the eggshell during development, which leads to selective accumulation of essential and non-essential elements in the embryo. Temperature and pH are two critical factors that affect the metabolism of marine organisms in the coastal shallow waters. In this study, we investigated the effects of pH and temperature…

    Everyone loves chemistry; it’s the difference between Pero and real coffee, Morton’s and sea salt. It’s the magic between Tracy and Hepburn. But on the larger scale, we take chemistry for granted and it’s killing us. The earth has an insidious chemical change going on through the vast majority of its surface area where the oceans meet, belly to belly, with the sky. Our skies, now laden with unusually high and accelerating levels of carbon dioxide, are tainting our oceans with carbonic acid in a process called acidification. It’s a reaction we learned about in…

  • Maine ocean scientist leads round-the-world study of climate change (video & audio)

    Anne-Marin Nisumaa

    You might have read this week about how our oceans are changing. A recent report by federal scientists confirmed what many fishermen already knew: the fish are on the move. Warmer waters are pushing species like cod, haddock and winter flounder further north, causing New England fishermen to have to go farther out to sea to get their traditional catch. Dr. Mike Sieracki from the Bigelow Laboratory for Ocean Sciences in West Boothbay Maine, has gone farther afield to study the effect of climate change. He’s currently off the coast of Malta in the Mediterranean, doing a stint aboard a…

  • Fish, salmon farms and empty oceans

    16 Nov 2009 | 12:42 am
    Anyone who cares about wild salmon and tries to reconcile the tolerant attitude of the Department of Fisheries and Oceans (DFO) to the environmentally damaging practices of salmon farming must confront a bewildering question. If DFO is responsible for the well-being of Canada’s wild salmon stocks, why does it endorse salmon farming in principle and allow open net-pens in practice when such an industrial practice is a clear risk to wild stocks and causes demonstrable harm to the very species and habitat that DFO is legally mandated to protect? … Concurrently, the emission of carbon…

    Skidaway Institute of Oceanography professor Dana Savidge has been awarded a research grant from the National Science Foundation for $207,450 to study ocean currents called Langmuir Supercells. Langmuir circulation cells occur during strong winds and waves, and appear as long lines of bubbles or floating material aligned with the wind on the ocean surface. “These lines are the surface expression of currents beneath the surface,” said Savidge. “The Langmuir cells are like huge counter-rotating jelly-rolls, aligned longways with the wind, with currents spiraling from the ocean surface…

  • doubt in filtering of sst data

    divyadavidt
    19 Nov 2009 | 10:20 pm
    Hi everyone............... I have a doubt dealt with the band filtering of SST data. When I did the same for OSCAR data I got the magnitude in the same order as that of the raw data,i.e., the current data in m/s for my region varies from 0.5 to -0.5 m/s and after doing band pass filtering the resultant values comes in the same order. But when I did the same for SST in Kelvin after converting it to deg C in the order 26 to 30 deg C, I am getting the filtered values as 6 - 8 deg C. Can anyone help in claryfying why I am getting such a difference in the band passed filtered sst. Thanks in…

  • The Last of the Bluefin Tuna?

    I’ve often wondered whether people who eat tuna from a can have any idea what a tuna fish actually looks like? How does a can of tuna still cost less than a dollar? Mainly because the average tin of tuna comes from smaller and less tasty species (usually albacore or skipjack at roughly $25 per pound), which are still plentiful in the oceans as they require less resources to survive and reproduce. In contrast, the closely related southern bluefin tuna commands upwards of $350 per pound, yet is IUCN listed as ‘critically endangered’. With commercial extinction looming on the…

A new study shows that corals spawn when regional wind fields are light. When it is calm, the eggs and sperm have the chance to unite before they are dispersed.

  • How do you camouflage yourself but stand out with your friends? Ask a cuttle, Part 1

    Christine Williams
    21 Nov 2009 | 8:29 am
    Sepia officinalis, photo C. Williams Mantis shrimp are not the only marine organisms to take advantage of polarized light in communication and defense; in fact, it can be argued that the cuttlefish pulls even more amazing stunts—camouflaging itself from predators while sending colored light signals invisible to everyone except other cuttles—all while only being able to see the color green. So how, and more importantly why, do they accomplish this? Cuttlefish skin, like that of other cephalopods, has evolved to be able to display an incredibly wide range of appearances, both in color and…

  • From revolution to evolution: a look at two hobby trends and their impact

    20 Nov 2009 | 11:39 am
    Photo from "Marine Atlas" by Helmut Debelius After 30-something years in the hobby, you see a lot of trends come and go. Fads and “new” ideas show up and subsequently vanish back into the mists of time. Some of these “fads” do stick around a while, yet many quickly disappear after we move on to the next big thing. You need only look back in recent  reef hobby “history” to see examples of what I mean: A few years back, Acanthastrea was all the rage. If you had one, it didn’t matter how ugly it was—you were the coolest thing this side of ORA! People were downright…

  • Steve Tyronne Limited Edition ‘Butternuts Boulder’ Porites

    20 Nov 2009 | 11:20 am
    The Butternuts Boulder Porites has an exciting combination of pigments. The center of the corallites contain a solid bright chocolate pigmentation. This contrasts rather well with the butternut tan pigments that develop on the corallite ridges. As can be seen in the closeup image above the corals colors are developed by pigments located in dense chunks or pigment sprinkles. Koral Hackerz acquired our seed colony from Renegade Reefers member StiffLeather. Julia acquired her original colony of this coral from Hacknpack.com who transhipped the coral in from Indo Polynesia. The coral was then…

  • Cool, bronzed antique aquarium and stand from the 1920s

    Steinhart Aquarium We always enjoy looking back on the hobby seeing how we’ve progressed over the years, so when we came across this antique, bronzed seahorse design aquarium from the 1920s on Off the Wall Antiques we had to share it. This 20-gallon aquarium was made 1926 by the Jewel Aquarium Co. of Chicago. The tank is old school slate bottomed with some very ornate seahorses added to the design of the stand very reminiscent of the famous seahorse railing of San Francisco’s Steinhart Aquarium from the same time period. The tank is “supported” on the side with bronzed dolphins to…

  • Shocker: cheap chinese-made pumps from Coralvue get recalled

    Jake Adams
    20 Nov 2009 | 8:00 am
    The High Seas Prop Pump aka Sun Sun pump from Coralvue can’t decide whether it is aping a Hydor Korallia, Tunze Nano Stream or both. It’s no surprise then that the cheaply made Chinese product has been recalled in Canada due to a couple reports of electrocution. We first wrote about the High Seas Prop pump at the Midwest Frag Fest where they sported some ridiculously cheap retail pricing.  In less than six months, the pumps have caused enough problems to be recalled in Canada and if problems arise in the US we could see an American recall as well. If you’ve recently…

  • How did the red sea get its name?

    askpari
    15 Nov 2009 | 3:29 pm
    Red Sea The Red Sea is a narrow sea that lies between the sandy shores of northeastern Africa and the Arabia Peninsula. It is called the “Red Sea” because the color of the water at times is actually red. The Red Sea could have gotten its name for several reasons.  The dry, desert lands surrounding the sea are a reddish color.  So are the coral reefs in the sea. And billions of tiny red plants called algae, growing in the hot, salty water, make the water look red in some places. The Red Sea is really a great crack in the earth that has filled with water. It is about 1,400 miles long, up…

    I spent last week in Malaysia wth my girlfriend, Waew. It was our first proper holiday together and my first proper trip to Malaysia (I did a brief border hop from Brunei in 2005 but that was essentially just to tick another country off the list). It was also my first proper holiday in South East Asia since moving to Thailand last year, having so far failed to live up to my promise to myself to see as much of the region as possible while living here. We flew in and out of Penang, where we spent half of the week. The other half we spent in Langkawi. It proved a decent mix of city and…

  • Humpback whales returning to Hawaii for the winter season

    31 Oct 2009 | 2:15 pm
    by B. N. SullivanWe're at the start of Humpback whale season here in Hawaii. Every autumn, large numbers of Humpbacks (Megaptera novaeangliae) migrate from their summer feeding grounds in the north Pacific to the waters around the Hawaiian Islands, where they then spend the winter. Those of us who live in Hawaii tend to feel a bit possessive about the north Pacific stock of Humpbacks, because they are born and bred in our waters.  Over the course of their winter stay in Hawaii, the big cetaceans mate, and the females who became pregnant the year before give birth to their calves.
