New ocean monitoring indicators: ocean acidification (video)

Ocean Monitoring Indicators (OMIs) are free downloadable trends and data sets covering the past quarter of a century. These are key variables used to track the vital health signs of the ocean and changes in line with climate change. Knowing how much heat is stored in the ocean, the pH of the ocean, how fast the sea levels are rising and sea ice is melting, is essential to understanding the current state and changes in the ocean and climate. This information is critical for assessing and confronting oceanic and atmospheric changes associated with global warming and they can be used by scientists, decision-makers, environmental agencies, the general public, and in measuring our responses to environmental directives. The OMIs expand the Copernicus Marine Service portfolio to provide not only ocean data products but also key reference information on the state of the ocean.

From dissolution to solution

Erickson and Crews consider solutions to ocean acidification and encourage students to maximize and expand their impact. While these lessons relate to ocean acidification, they could be incorporated into a larger unit on climate change or human environmental impacts. They also provide a brief overview of the Changing Ocean Chemistry module.

Ocean acidification investigation

Carbon dioxide contributes to greenhouse gases that trap the Sun’s reradiated heat, causing global warming, which also means ocean water is warming. While other human activities are affecting seawater’s acid-base balance and may be important locally, their total effect is small in comparison with the changes driven by rising atmospheric carbon dioxide (WHOI 2018). The investigation should answer the question: “When water increases in acidity, how does it impact underwater plants and/or seashells (depending on which materials you are using)?” Once students have written their hypotheses, materials, and procedure into their science notebooks, lead a whole-class discussion emphasizing the need to hold all variables constant, except the one being tested (water acidity). Evaluate Ask students to draw a model that shows a causeand-effect chain: the burning of fossil fuels (in power plants, transportation, and factories) to less seafood in the supermarket.

Masters opportunity: animal eco-physiology and climate change

Application deadline: 15 February 2019

Location: University of Hamburg, Germany

Description: This internship/masters project be start in April 2019 at the Institute for Ecosystem and Fisheries Sciences at the University of Hamburg, Germany. The position is within “CLIMAR”, an international project examining the impacts of ocean acidification and warming on marine animals. The successful candidate will work with embryos and larvae of ecologically impartant fish (Belone belone and/or Clupea harengus). The candidate will conduct short-term experiments examining physiological traits of the Baltic fish such as:
development, survival, metabolic rate, heart rate, biochemical analyses of cellular defense mechanisms and swimming performance, in response to increased CO2 and increased temperature.

Qualifications: The candidate should have:
– a bachelor with experience and interest in animal physiology, ecology or a related discipline
– experience or interest in the laboratory cultivation of marine organisms
– knowledge of the design of controlled laboratory experiments is helpful
– knowledge of ecophysiology and development of marine fish is helpful
– the ability to take responsibility and work independently

For more information, contact Katharina Alter (katharina.alter@uni-hamburg.de)

IMOS marine data and science e-lectures

Australia’s Integrated Marine Observing System, in collaboration with the Institute for Marine and Antarctic Studies from the University of Tasmania, has developed a series of marine data and science e-lectures designed to help marine scientists learn how to use IMOS ocean observation data in their research.
These lectures includes 3 topics Marine Primary Productivity, Marine Carbon Cycle and Ocean Acidification, all of which are relevant in all oceans. The lectures include Power Point (PPT) presentations (narrated and non-narrated with transcripts) and laboratory material in Python and/or R and Matlab with quiz exercises and data files taken from the AODN.
http://imos.org.au/news/newsitem/new-imos-marine-data-and-science-e-lectures-series-released/
While the lectures are looking at these topics at different Australian locations, most of the material generated can be adapted and use for any location around the world.
The material has been set up in the UTas Open2U system, which is an open source system that can be accessed anywhere in the world and it is set up mostly for self-learning.
We are now live and you can find all the lectures through: https://open2u.utas.edu.au/Course/4261
To access the material people need to register, if they are teachers they need to register and then let me know (ana.lara@utas.edu.au) so I can grant them access as teachers to access the material in a quick and easy way (compiled as a zip file for teachers).
We welcome all feedback so please let us know what do you think about the lectures and if there are any way we can improve this.

Ocean acidification can affect seaweed and humans (podcast)

Ocean Acidification is usually discussed with the subjects of calcium based animals such as Corals, mussels and snails as they need Calcium to build their shells. Calcium will not be available as there is more CO2 in the Ocean. However, not all living Ocean beings will be negatively affected. Plants such as Seaweeds are predicted to thrive.

Many sushi lovers will breathe a sigh of relief at this news, but there is cautioned thrown their way. A new study was recently conducted on how the iodine levels in seaweed, and its consumers, will be affected in the presence of elevated CO2 levels as future IPCC reports suggest.

Iodine is important to humans as it regulates the thyroid hormones in your body. Too little or too much iodine could have serious effects on the body that could decrease human and animal health.

The results show consumers (fish and molluscs) that ate seaweed under increased CO2 conditions possessed elevated iodine concentrations, which means humans will be required to monitor the iodine levels in seaweed in the future to ensure it does not decrease the health in humans.
