Our 4 baskets are here but at least 2 are sitting on the bottom. 

 

 

The day was cold.  The 4 baskets look good.

They were pulled out & cleaned.   

Volunteers from DC Strokes worked with Kyle.

The light was fading rapidly as we worked to 

complete the measurements

This might be the last measurement session here.

The baskets will be moved 2/9 to KAG where they will

be safer from winter weather.

                    

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

These smart volunteers brought a CANOPY with them!  Made the

Working in teams, the volunteers measured length and weight of 

25% of the mussels in each basket. (25 out of 250 mussels)

 

Using calipers to measure mussel length

 

Weighing each mussel

 

Recording length and weight

Replacing basket covers and securing with reusable zip ties.  Third basket fr left is the replacement - we're hoping this one stays afloat 

 Four baskets in place again, tied together with ropes, and floating off the seawall.  The Mussel Team:  

 

 Next Quarterly Monitoring Session - October  

Bring paper towels, bucket
