Shellfish Beds in Great Bay,
Little Bay and the Oyster River. This map, developed for the New Hampshire
Estuaries project and published in the Technical Characterization of
Estuarine and Coastal New Hampshire indicates the location and aereal
cover of softshell clam (Mya arenaria) and Eastern oyster (Crassostrea
virginica) beds in Great Bay, portions of Little Bay and the Oyster
River, NH. The map was developed from data generated by the New Hampshire
Fish and Game (Ayer et al. 1970, Nelson 1982, 1991), and scientists from
the Jackson Estuarine Laboratory (Langan 1997, 1998). Information on current
shellfish densities and change in abundance over time can be found in the
reports cited.

Softshell clam beds in the Hampton
Harbor Estuary. This map, developed for the New Hampshire Estuaries project
and published in the Technical Characterization of Estuarine and Coastal
New Hampshire indicates the location of softshell clam beds in the Hampton
Harbor. The data was generated by Normandeau Associates, Inc. (NAI 1996)
for Northeast Utilities.

Macroalgal distribution in the
Great Bay Estuary. This map of occurrences of seaweeds in the Great Bay
Estuary was developed for the for the New Hampshire Estuaries project and
published in the Technical Characterization of Estuarine and Coastal
New Hampshire was developed from data generated by Mathieson and Hehre,
1986, Mathieson and Penniman, 1991 and Banner and Hayes 1996.

Changes in eelgrass (Zostera
marina) cover in Great Bay from 1986 to 1992. This series of maps
which are published in the Technical Characterization of Estuarine
and Coastal New Hampshire, show the change in eelgrass cover from the
mid 1980’s through the early 1990’s. The declines were attributed
to an outbreak of the eelgrass wasting disease that is caused by the slime
mold Labyrinthula zostrea. This decline was followed by rapid recovery
through natural seed production and revegetation. The maps were generated
from data collected by Short et al. 1986, Short and Mathieson 1992, Short
et al. 1992, 1993 and Burdick and Short 1995.
Slideshow of the 1986 to 1992 time series.

Eelgrass density in Great Bay,
NH, 1992. This map, which is published in the Technical Characterization
of Estuarine and Coastal New Hampshire was based on data generated in
1992 by Frederick Short using aerial photography, georectification and ground
truthing.
