Pilings that the trestle is built on are counted in sets from the shore out to 100 pilings from the shore, each piling set had 8 samples sites surveyed, one in the very center then at ten foot distances four samples to the north and three samples to the south. Most sample sites were under water so oysters and substrate were gathered in a bucket and inventoried and recorded at drier ground. The data gathered this week, along with additional data that we will collect at the next set of low tides, will show how far and densely the oysters have spread on their own and will allow comparison with previous years data. This years sampling is the largest undertaking yet.

I was surprised by the amount of oil still leaching from the creosote pilings which Dr. Dinnel said are about 100 years old. It amazes me that people still clam under and near the trestle. Not only is oil sheen present within rotting pilings but oil is also leaching into the surrounding soil so at times when you walk you release oil and sadly the tide carries it away.
The weather steadily improved throughout the week which was nice and encouraging. Because the bay is shallow and large the water that remains at low tide is surprisingly warm, during bad weather the water was actually warmer than the ambient air.
|Early in the week rain and wind, I'm not a hunchback my backpack is under my coat to stay dry.|
|Later in the week sun and mud!|
