Description

Eelgrass Climate Impacts
Experimental conditions, growth and survival of eelgrass
Leaf morphometric data measured on 3 to 5 shoots in each tank
Experiment codes refer to specific populations and plantings:

Experiment Code	Start Date	Population
1	May 2013	South Bay, Virginia Transplants
2	April 2013	Dumas Bay, Washington

Methods & Sampling

Leaf morphometric data were measured on 3 to 5 shoots in each tank once each month beginning in May 2013. The total length of each leaf on a shoot was measured to the nearest mm using a flexible meter tape. Widths were measured with a digital caliper. Experiment codes refer to specific populations and plantings:

Experiment Code	Start Date	Population
1	May 2013	South Bay, Virginia Transplants
2	April 2013	Dumas Bay, Washington

Data Processing Description

Leaf morphometrics - Growth rates were determined using the hole-punch method. Growth rates were determined by measuring (1) the total length of each leaf on each shoot and (2) the distance from the original punch mark on the outer sheath to the existing hole on each leaf (Zieman and Wetzel 1980, Zimmerman et al. 1996). Replicate measures within each tank were averaged to produce single values for each experiment code.
