INTRODUCT ION

water quality and sediment surveys in Little Neck Bay,

Manhasset Bay, Hempstead Harbor, Huntington Harbor, Port Jefferson

Harbor and Mt. Sinai Harbor were conducted by the Marine Sciences

Research Center during the period May-December, 1971. ~1e

location of these bays is shown in Figs. 2 and 9. ~1e surveys,

sponsored by the Nassau-Suffolk Regional Planning Board, were

part of a project designed to establish physical and chemical

criteria for assessment of environmental quality in the bays

(Gross et al, 1972). This report presents the sampling procedures

and analytical techniques used in the surveys. The cruises are

outlined in Tables 3 and 4. Figures indicative of the entire

body of data (which is stored at the Marine Sciences Research

Center) are presented for six harbors in Nassau and Suffolk

Counties.

Shipboard Instrumentation

The semi-automated data acquisition system developed by

p.ersonnel of the Marine Sciences Res'earch Center for water

analysis and sample collection while on station was installed

on the R/V MICMAC (Hardy, 1970~ Hardy and Weyl, 1971i Glen Hulse,

personal communication). The system consisted of a submersible

well pump (Sears, Roebuck and Co., Brooklyn, N.Y.) affixed to

61 meters of 19 millimeter (internal diameter) rubber hose (Fig. 1).

The pump was rated at 1000 gallons p ·er hour and the hose had a

measured flushing time of 35 seconds. A glass probe thermistor

(Fenwal Electronics, Model GB 32MM172, Framingham, Mass.) attached

to the pump intake permitted recording of temperatures during

sampling. The depth of water beneath the sampling points was

determined by a transducer (Apelco MR-201B, San Francisco, cal.)

attached to the pump. Ship drift during sampling could be

monitored from the depths registered by the transducer. ~1e pu~p

hose was connected to the electronic instrument system on the

R/ V MICMAC with polyvinyl chloride plumbing. A Hytech salinometer

(Model 6230, Bissett-Berman, San Diego, Cal.) was modified to

permit a continuous flow of seawater from the pump through the

unit. water samples for chemical analysis were drawn from out

lets in the plumbing. Dissolved oxygen was measured with a

Yellow Springs Model 54 oxygen meter (Yellow Springs, Ohio).

The oxygen probe was placed in a double-chambered plexiglass

cell. The inner chamber, containing the sample, the 02 sensor

and a thermistor, could be drained to permit calibration of the

sensor in air. The outer chamber was connected to the submersible

pump continuous flow line, and contained sample water which cooled

the inner chamber, permitting air calibration of the oxygen probe

at essentially in situ water temperatures.

The station sampling procedure consisted of lowering the

pump to the maximum station depth, starting the pump and allowing

the hose to flush for several minutes. Temperature, conductivity,

and oxygen concentrations were then recorded and water samples

drawn. Ti1e pump was raised at varying intervals to permit

sampling of the water column.

A~onia, nitrite, nitrate, phosphate and chlorophyll concen

trations were determined by analytical procedures (Table 1)

adapted from Strickland and Parsons (1968).

S~diment Analyses

Surficial sediment samples from the bays were collected by

using a Shipek grab sampler (Shipek, 1965) operated from the

R/V MICMAC. The samples were placed in plastic bags and kept

under refrigeration until their delivery (on the day of collec

tion) to the Marine Sciences Research Center where they were

frozen pending analysis (Table 2).

Sediment grain size distribution was determined by sieve,

settling tube (Emery, 1938) and pipette analyses (Galehouse, 1971).

The data are reported as median grain diameters in millimeters.

Sediment sorting, or the uniformity in grain size of a sample, is

expressed by the graphic standard de viation of Folk (1968).

Reported in phi (f) units, the graphic standard deviat:.ion measures

the tendency of the grains of a sample to cluster around the

sample median grain diameter. The degree of sediment sorting

decreases as the graphic standard deviation increases. A crude

measure of the abundance of organic ~atter in sediment was

provided by loss on ignition (Gross et aI, 1971).

Interstitial or pore waters occupy the spaces among the

grains in sediment deposits. Interstitial water content in a

sediment sample is reported as water loss. An initial extraction

process precedes the nutrient analyses of the interstitial water.

Distilled 'water is added to the wet sediment sample, and the

mixture is stirred and allowed to settle. The liquid portion of

the mixture is then separated and filtered by a 0.8 ~ Millipore

filter. The filtrate is then analyz e d for ammonia, nitrite,

nitrate and phosphate content by the same analytical techniques

used for the water column samp les (Table 1).
