Figure 2. Map of portions of
southeastern Massachusetts, Cape Cod, and Buzzards Bay. Moorings in Buzzards
Bay and Cape Cod Canal are indicated with a red circle and mooring number (859,
860, and 862). Bathymetric contours are in meters, referenced to mean low
water. Box indicates inset for figure 3.

Figure 3. Map of West Falmouth
Harbor, Massachusetts. Moorings in West Falmouth Harbor are indicated with a
red circle and mooring number (882, 883, 884, 885, 886, 887, 888, 900, and
901). Bathymetric contours are in meters. FWTP, Falmouth Wastewater Treatment
Plant. |

Figure 4. Tripods prior to
deployment in Buzzards Bay (moorings 859, 860). |

Figure 5. Side-looking ADCP
(SL-ADCP) before deployment on the rudder of the T/S Kennedy (mooring
861). Two acoustic transducers allow for estimation of two-dimensional
horizontal velocities; three- and four-transducer ADCPs estimate
two-dimensional horizontal velocities and vertical velocities. |
 |
Figure 6. Position and schematic of beam spread for the
SL-ADCP deployed on pier, facing entrance channel to West Falmouth Harbor
(mooring 901). Actual beams traveled over 20 meters into the channel before
interference with the channel bed and water surface (due to
beam vertical spreading).

Figure 7. Upward-looking
Nortek Aquadopp and Sea-Bird 39 PT sensor deployed on the seabed (moorings
882, 885, 887). White paste on transducers is zinc oxide, used to reduce
biological growth, which interferes with signal transmission.

Figure 8. Satlantic ISUS nitrate
sensor and YSI 6920 multiparameter sonde deployed on floating dock at
0.12 meters below surface (mooring 883).

Figure 9. Sea-Bird MicroCATs deployed on a
vertical tower array (mooring 884). Three sensors were mounted on this
array at 0.33 meters above bottom (not visible), 0.55 meters above bottom,
and 0.77 meters above bottom.

Figure 10. Aanderaa RCM9 with optical dissolved oxygen (DO)
probe and YSI 6920 multiparameter sonde, deployed on the seabed using a
pedestal mount (mooring 886) 0.3 meters above bottom. Mooring 888 used a
similar mount, with only a YSI multiparameter sonde.

Current Sensor; DCS) and optical dissolved oxygen (DO) probe mounted on
seabed (mooring 900).
