Lost at sea: Ecological assessment around a sunken shipping container
Thousands of shipping containers are lost from cargo vessels each year. Many of these containers eventually sink to the deep seafloor. In 2004, researchers at the Monterey Bay Aquarium Research Institute (MBARI) discovered a lost shipping container almost 1,300 meters (4,200 feet) below the surface of the Monterey Bay National Marine Sanctuary. In the first ever survey of its kind, researchers from MBARI and the Sanctuary recently described how deep-sea animal communities on and around the container differed from those in surrounding areas. The red dots seen in some of the underwater footage are lasers mounted on the remotely operated submersible. The lasers are 29 cm apart and allow the scientists to estimate animal size.

Sponges of the Caribbean: What ecological factors most affect them?
Joeseph Pawlik University of North Carolina, Wilmington Sponges are animals that eat tiny food particles as they pump water through their bodies. They are very common on Caribbean coral reefs, and come in all shapes, sizes and colors. Previous research concluded that sponge growth is most limited by food particle availability. But sponges are also used as food by angelfishes that nibble on them, decreasing their growth. Which is more important, food or predation? We tested both possibilities by putting sponge pieces inside and outside of protective cages in shallow water, and in deep water where there are more food particles. After a year, sponges in cages grew a lot more because they were protected from angelfishes, but sponges did not grow more in deep water. Therefore, sponges are more affected by predation than food. Removal of angelfishes by fishing may result in sponges overgrowing and killing the corals that build coral reefs.

Marine Pollution
The ocean covers almost three quarters of our planet. Populations in coastal regions are growing and placing increasing pressure on coastal and marine ecosystems. Marine pollution of many kinds threatens the health of the ocean and its living resources. While the past decades have seen efforts at the local, national, and international levels to address the problems of marine pollution, more needs to be done. Learn more about marine pollution at www.state.gov/ourocean.

Madingley Model: Global Dynamics of Total Animal Biomass
The Madingley Model simulates how the structure and function of ecosystems at global scales emerges from the underlying ecology of individual organisms. Think, simulating the fate of every single organism on Earth*, from the smallest to the largest, on land and in the sea, for tens or hundreds of years. The Madingley Model was developed at Microsoft Research, Cambridge, UK; and UNEP-WCMC, Cambridge, UK. See http://www.madingleymodel.org/index.html Ths video shows the emergent dynamics of total animal biomass at global scales. Note that the maximum total animal biomass is greater in the oceans; and that on land and in the ocean, the total animal biomass is often highly seasonal. This seasonality is ultimately driven by seasonal cycles in light, nutrients, mixing depth and currents (in the ocean) and temperature, precipitation and other climatic factors (on land). These seasonal focings affect both the plants (which are the source of food for the animals) but also the animals themselves (e.g. temperature affects metabolism; and ocean currents affect dispersal).

Australian sea lion foraging ecology research, Bunda Cliffs, South Australia
Australian sea lions are listed as endangered by the Australian Government EPBC Act. They are thought to be vulnerable to decline due to (i) already small overall population size (~17,000 animals), (ii) extended breeding cycle (17-18 months, which reduces lifetime fecundity), (iii) breeding site fidelity or philopatry (where adult females always return to their place of birth to breed, thus extinguishing the possibility of depressed or extinct breeding sights recovering), and (iv) genetically isolated and very small sub-populations (as a result of philopatry, with about one third of the ~70 breeding sites producing less than 30 pups each breeding cycle). One of the handful of known threats to the conservation of the species is by-catch mortality in demersal gill-nets set in South Australian shelf waters to catch large amounts of gummy and school shark, which makes up the bulk of fish used in the 'fish and chip' trade in southern Australia. About 86% of the species resides in South Australian waters, suggesting the two are likely to frequently overlap. The tracking by satellite transmitter of individual females provided valuable insights into where they go to forage when at sea. Overlapping their 'tracks' with data collected on the distribution of gill-net fishing effort enables the areas of particular concern to be identified. The results of the Bunda Cliffs deployments depicted in this video clip, along with the tracks of individuals tracked from more than 16 other breeding sites on islands adjacent to the South Australian mainland, have been used to inform managers on where a network of 'fishery exclusions' or 'spatial closures' should be placed. At present, the network of closures actually in place are based more on negotiated outcomes between stakeholders (i.e. conservation and fishery managers, each of whom have opposing legislative mandates). Working from the Bunda Cliffs posed the greatest challenge of any of the sights visited for this generally large and logistically difficult study. It's imposing 120m cliffs acted as a barrier to accessing the colony, with the only possible access over the edge. The professional approach of the local Ceduna SES Cliff Rescue team made that possible. The study was largely funded by FRDC, SARDI and NHT, with the GABMP-MC providing funds and in-kind support specifically for the Bunda Cliffs work. The project was coordinated by Dr Derek Hamer and the video clip itself was funded by the GABMP-MC and put together by ???.

How Whales Change Climate

"When we try to pick out anything by itself, we find it hitched to everything else in the Universe." - John Muir When whales were at their historic populations, before their numbers were reduced, it seems that whales might have been responsible for removing tens of millions of tonnes of carbon from the atmosphere every year. Whales change the climate. The return of the great whales, if they are allowed to recover, could be seen as a benign form of geo-engineering. It could undo some of the damage we have done, both to the living systems of the sea, and to the atmosphere.

Freshwater fish vs seawater fish ion regulation-Animal Physiology
"Fish gills regulate ion differently in freshwater and saltwater." Marine water fish blood has a higher water concentration than their surrounding sea water. causing water molecules to diffuse out of the blood into their surrounding water by osmosis. These fish must replace the lost water, by the drinking their surrounding concentrated water, intaking salts which is then removed by active transport through their gills Na+-Cl- ATPase molecules, back to the seawater. Ion exchange in saltwater fish: The Na+ K+/2Cl- (NKCC) co-transporter brings in potassium ion (K+) and chloride ion (Cl-) from the extracellular fluid in the fish gill epithelial cells using the Na+ electrochemical gradient. The K+ and the Na+ separate from the 2Cl- in the the cell. The 2Cl- separate out and exit the cell through the apical surface via the Chloride channel down their concentration gradient. the K+ goes back to the extracellular fluid via the K+ channel from the cell. Na+ exit the cell that had entered through the NKCC via the Na+/K+ ATPase channel in exchange for K+ causing small potential difference (outside more negative due to the Cl- ions exiting than compared to the extracellular fluid) it drives the outward movement Na+ outside the cell. In freshwater fish water is absorbed through gills and skin by diffusion into the blood. While water moves in towards the higher osmotic pressure of the blood, Na+ and Cl- ions diffuse out of the fish, moving down their concentration gradients to the external environment. The fish then can actively take up the ions across their gills epithelial membranes from the surrounding environment to replace the constant loss of ions. Food is another way by which to replace lost Na+ and Cl-. Ion regulation is freshwater fish: The mechanism for Na+ uptake and Cl- are independent. From the dilute freshwater to the concentrated blood Na+ is actively transported against the concentration gradient. H+ is excreted out in exchange for Na+. The Cl-/HCO3 - exchange secretes the bicarbonate ion (HCO3-) in exchange for Cl- ions. HCO3- and H+ are metabolic wastes that are derived from the conversion carbon-dioxide(CO2) using carbonate anhydrase (CA). These metabolic wastes (H+ and HCO3) keeps it from generating large potential differences across the gill epithelium in freshwater fish. A protein that is responsible for sodium uptake uses ATP to exchange Na+ for K+.

Introduction To Marine Life Course: Whales, Dolphins & Porpoises
This course gives students of all ages a wonderful introduction to the marine life of British Columbia. Building on the Aquarium’s successful research and education programs, the course will introduce participants to a variety of sea creatures found along the shores of B.C. Whales, Dolphins & Porpoises Tuesday, September 30, 2014 Dr. Lance Barrett-Lennard has a broad range of research experience in the field studies of marine mammals, with a particular focus on killer whales. He has been an active collaborator in the ongoing studies of the behavioural and population biology of killer whales in British Columbia and Alaska since 1984, and has also studied the species in Norway and the sub-Antarctic. Carla Crossman is an East Coast native and grew up around the water with a love of the ocean and a passion for the protection of biodiversity through research and public outreach. She has an undergraduate degree in biology from Queen’s University and studied porpoises for her master’s degree at UBC. Carla currently is a marine mammal research biologist for the Vancouver Aquarium Cetacean Research Program. Tessa Danelesko was raised in Calgary, Alberta and fell in love with the ocean during summer vacations exploring the shores of Vancouver Island. She attended the University of Victoria and completed the Combined Biology and Psychology BSc program. She has experience working and volunteering for a variety of marine conservation and research projects that have taken her around the globe and she is currently the Coordinator for the B.C.

Our ever-changing deep sea: Dramatic shifts in seafloor communities
Our knowledge of the ocean has increased tremendously with the advent of new technologies. How deep-sea animals can exist in places where no food is produced has long been a mystery. The seafloor in the abyss off the coast of California was studied for 24 years, and these investigations are contributing to our understanding about how conditions at the surface of the ocean control deep-living biological communities.

Marine ecosystem
Marine ecosystems are among the largest of Earth's aquatic ecosystems. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content. Marine waters cover two-thirds of the surface of the Earth. Such places are considered ecosystems because the plant life supports the animal life and vice-versa. See food chains. Marine ecosystems are very important for the overall health of both marine and terrestrial environments. According to the World Resource Center, coastal habitats alone account for approximately 1/3 of all marine biological productivity, and estuarine ecosystems (i.e., salt marshes, seagrasses, mangrove forests) are among the most productive regions on the planet. In addition, other marine ecosystems such as coral reefs, provide food and shelter to the highest levels of marine diversity in the world. This video is targeted to blind users.
