APPENDIX C

Data/Information and Research Needs Relative to Humpback Whales in Glacier Bay and Elsewhere (these lists are examples and not necessarily all inclusive).

A. Compilation and a.n.a.lyses of existing data (available data presently are not in a form that is optimally useful)

I. =Whales=

a. whale distribution and abundance in Glacier Bay and surrounding areas--by year, season, time of day, age, s.e.x, weather (tide, rain, etc.), birds, boats (by total and by cla.s.s), depth of water, distance from sh.o.r.e, prey species, effort,----

b. movements/habitat use patterns--home range, temporal/spatial distribution of sightings of individually recognizable animals--are there resident, migratory and/or transient animals in the Bay or surrounding waters--do individuals have seasonal, annual cycles as to when/where they occur

c. undisturbed ("normal"--baseline) whale behavior--by age, s.e.x, group size, group composition, time of day, season, location (descriptive and quant.i.tative)

1. resting dive times/breathing a. vocalization 2. traveling 1.

3. feeding 2.

i. lunge-feeding 3.

ii. bubble net-feeding "

iii. other b. tail lob c. raking d. finning e. breaching f. avoidance g. other

4. interaction with other whales/social organization of whales

d. disturbed whale behavior--stimulus/response--behavior (as above) before, during and after an event--response distance (by age, s.e.x, pre-event activity, location, time between events, time of day, season, weather, etc.)--recovery time (by age, s.e.x, etc.).

II. =Boat and Aircraft Traffic=

a. distribution and abundance in Glacier Bay and surrounding areas--by type (cla.s.s), year, season, time of day, weather

b. movements/use patterns--by type, year, etc.

c. activities (behavior)--by type, year, etc.

1. whale watching 2. fis.h.i.+ng (sport/commercial)

III. =Habitat= (physical, chemical, biological environment--by year, season, etc.)

a. physical--water temperature, sediment load

b. chemical--salinity, oxygen content, inorganic nutrient, pollutants

c. biological 1. distribution and abundance of primary and secondary prey species--by year, season, time of day 2. distribution, size, and species composition of fish catch, including by-catch--by year and season 3. distribution and abundance of predators (killer whales) and compet.i.tors other than man--by year, season, time of day, etc.

B. Improve base line data

I. =Acoustic=

a. ambient noise levels--representative areas (in and outside Bay), seasons, time of day, weather and tide conditions, sea state

b. boat- and plane-related noise--representative types, representative areas (in and outside Bay), speed (prop rpm), season, time of day, sea state

II. =Whales=--in and outside the Bay

a. abundance

b. distribution

c. movements (habitat use pattern)

d. activity patterns

e. behavior vocalization

f. habitat requirement/areas of special significance

III. =Boats and Planes=--in and outside the Bay

a. abundance--by type, season, time of day

b. distribution-- " " " "

c. movements-- " " " "

d. activity in patterns " " "

IV. =Habitat=

a. physical

b. chemical--pollutant levels

c. biological

1. distribution, abundance and dynamics of primary and secondary prey species--in and outside the Bay
