Information to be Derived:
Summary of Activity and Data Gathered: Two gravity cores were collected at a site near Parker Creek as follows: PK2000-1 38deg33.9395 N, 76deg26.6730 W, 16.4 m, recovery 240 cm, 8 porewater samples at 25 cm spacing; PK2000-2 38deg33.9418 N, 76deg26.6826 W, 16.2 m, recovery 230 cm, 23 porewater samples at 10 cm spacing. Samples analyzed onshore for total methane by Pohlman at NRL, chloride by ion chromatograph at MBL by Bratton.
