See the Tidal Bore

As mentioned in class, the tidal bore is an interesting phenomena that occurs right here in Nova Scotia. I have had the opportunity to see it numerous times. I have also been chased by the bore itself.
WIDE OPEN WILDRNESS is a family camp ground that is situated just off the Shubenacadie River. From this camp ground you have the opportunity to witness this event from a great vantage point (picture as left- I cant remember if that is the tidal bore in the picture or not- sorry.), as you can go down and walk along the river bed and do a tidal bore run, Which I can garentee will be one of the best times you will ever have. After wards you can go mud sliding and maybe later rapid rafting.

The website has some great pictures as well as any other information you might have about WOW camp ground.

Ocean Acidification network

This is an excellent website for anyone who wants clearly written information on ocean acidification. I found this website easy to understand, and explains the process of acidification very clearly. There is a Q and A section that answers many questions that I had, and did so in a way that was easily understood.
This website is very eye catching and easily manuverable. The information also comes from reputable sources. I recommend this site for anyone who need information on ocean acidification.

Acidification

For just about any information you need on ocean acidification, the fallowing report by Kleypas et all, 2006, is a very useful reference. In this workshop report the authors detail just about every aspect of ocean acidification from Carbonate chemistry, calcificaton response to technology used to conduct these studies. This report outlines what is known currently about acidification and where more research is needed.
If you feel that ocean acidification is something you would like to look into further, Start with this report.

Information on Ocean acidification measurements.

3 things to measure in Ocean Acidification.
dissolved Ca
dissolved CO3
Particulate CaCO3


Ca can usually assumed to be constant with salinity, and is computed using a complicated set of equations.

CO3 cannot be measured directly. First you must measure Alkalinity and dissloved inorganic carbon, and/or pH. The you can calculate CO3

Particulate CaCO3 is not commnly done for water samples because the samples are too small. More common for sediments. You take the same, acidify it and then capture the CO2 gas

John Largeir Talk

On October 21 Oceanographer John Largier from Bodega Marine Laboratory in California will be talking at Dalhousie University about the "zone of impact", coastal pollution and ocean characteristics.
This is a free talk and will be at the Tupper building on University Ave at 3:00 pm in theatre A.

fishing for the future

Fishing is a big deal in Nova Scotia. In fact, fishing is arguably the reason Nova Scotia was settled in the first place. Wars between the french and eanglish were faught over the last fish stocks Nova Scotia possessed.
Now its getting harder and harder to find fish to catch. This is a BIG problem for Nova Scotian fisherman. This artical proposes a way to fix this declining fish population, whether or not it is possible to do, is whole other bag of fish.
