INTRODUCTION 
This study is a survey of the Foraminifera from the Hadley Harbor 
Complex. Its purpose is to outline the distribution of the species, 
measure their diversity, and examine the relationship of these faunal 
characteristics to the environmental subareas of the Complex. 
The Hadley Harbor Complex lies about 6 miles southwest of Woods 
Hole, Massachusetts. The general configuration of the area is shown 
in figure 1. Parker et al (1964) have outlined four environments or 
subareas within the Hadley Harbor Complex. They are: (a) chan- 
nels; (b) Vineyard Sound channels; (c) inner harbor; (d) outer 
harbor. For the purpose of this study the channel a and b subareas 
will be combined. These channel subareas are shown as “gutters” in 
figure 1 . Fligh velocity currents sweep diurnally through these chan- 
nels and the Vineyard Sound gutters are also subjected to strong wave 
action. Sediments in the gutters are variable, but usually are coarse 
sands. The second subarea of this study, called the inner harbor, 
includes the area so labeled on the map as well as the deeper area of 
Hadley Harbor itself. This inner harbor subarea has quiet waters 
and deposition of silts and clays. Finally, there is the outer harbor 
subarea, which is subjected to moderate circulation and wave action 
and has a sandy silt bottom. This subarea includes the area just south 
of the Vineyard Sound gutters as well as the shallower areas of Had- 
ley Harbor itself. Much of the area except for the high-energy gut- 
ters and sand flats of the outer harbor contain seasonal eel grass.
