Time refers to 180th meridian and is correct within 5 minutes.

TT and TT, are given to the nearest 0.5° F. (.0 or .5) and are correct within 0.5%.
TzTx and T,T, are correct within 1° F.

They were read to the nearest 0.5° (.0 or o5)e

RR is correct within 0.01 assuming a representative catch.

For exposure see General Note

TABLE 13.

EIMER:

BI-HOURLY TEMPERATURES.

Bi-hourly temperatures are taken from the hygrothermograph, with the trace adjusted to fi
the direct-reading (psychron) and maximum and minimvalues.

Values shown in the Table are a

correct within 2° F. and from the close agreement between direct readings and thermograph read:
ings it is estimated that 9 out of 10 values are correct within 1° F.

The footnotes to the

Table give extreme values not obtainable within 1° by interpolation fram the bi-hourly values.

Since the hygrothermograph chart was usually checked daily (and always at least every
other day) times are correct within 15 minutes.

LAGOON TRAVERSES.

ZONES are defined as follows:
ZONE 1 -- Within 500 yards of KIMER
ZONE 2 -- Between 500 yards and 5 miles out from EIMER

(or, in two instances, from BRUCE)
ZONE 3 -- Between 5 and 8 miles out from ELMER
ZONE 4 -- Between 8 and 11 miles out from EIMER
ZONE 5 -~ Within 500 yards of MACK

Placement within zones is certain in every instance except the following:

On August 26th,

the 1030 observation was near the boundary between Zones 3 and 4, and may have been a few

hundred yards within 3, rather than in 4 as given.
observation on August 28th.

The same is true with reference to the 1015

In all instances except when the traverse originated at BRUCE,
