These Notes apply also to Table 28.
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.

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.
