Introduction

The current activities of the USC Arctic Project range from

taxonomic descriptions of Arctic zooplankton to physiological and

biochemical investigations of the adaptations of selected species.

In this report we summarize only those activities and findings

which are immediately related to the taxonomic contributions of

the project.

It is clear to all students of Arctic biology, that much

remains to be done. When a present day biologist directs his

j attention to the Arctic, he is immediately faced with the problems

of the identification of the organ'-'.-ms which are found there as

well as with the small amount of background information on the

biology of the animals which is usually necessary in order to

design appropriate ecAperimeits. With these two problems in mind,

the main thrust of our taxonomic effort has been directed towards

tie identification of the marine fauna and producing taxonomic

guxides which will enable any biologist to readily identify Arctic

zooplankton. Furthermore, through systematic collections in terms

of tirae and deptho we have been able to carry out additional studies

on -he biology of selected species which in our estimation contri-

bute sign:ificantly to ecology of the Arctic Ocean.

This report covers the period from September 1969 until

October 1972

Taxonomic Guides

To assist o-her members of thi3 project as well as other

scientists interested in Arctic biology, we have prepared a series

c practical taxonomic gmides to aid in the identification of Arctic

zooplankton. Of great help in the production of these guides was

the fact tt,.t the University of Southern California had been en-

gaged in surveys of the Arctic fauna for almost two decddes.

A large amount of taxonomic information was thus already on hand.

The guides have beer prepared in such a manner that even the non-

specialist can use them readily. They have been published as

technical reports entitled "Taxonomic Guides to Arctic Zooplankton",

in six separate issues:

Zooplankton (I): Amphipods of the Central ArcticEuphausiids of the Arctic Basinand Peripheral Seas

Zooplankton (II): Medusne of the Central ArcticSiphonophores of the Central ArcticCtenophores of the Central Arctic

Zooplankton (III):Species of the Arctic Ocean ChaetognathsPteropods of the Central ArcticDecapods of the Central Arctic

contributions (pp. 13-14).

Preparation of these guides required identification of organ-

isms collected earlier in the central Arctic from the ice stations

(ARLIS I, II, and T-3) and the nuclear submarines, Sea Dragon and

Sea Skate. Scattered collections from peripheral seas made from

drifting ice stations and coast guard cutters, Northwind (Sept.

1963), Burton Island (Sept. 1960), and Eastwind (July-August 1967)

were also examined. Because material collected from peripheral

seas was relatively small, the generalized guides to species in

most cases, could only be constructed for central Arctic zooplank-

ton. The guides, however, provide enough information of general

nature which is applicable to the principal taxonomic groups and

can be useful to scientists who work on zooplankton from the

peripheral seas as well.

Each guide Consists of dichotomous keys and illustrations of

adult zooplankton anatomy. All have been constructed so that very

little or no dissection of the specimen is necessary for identifi-

cation. Pertinent references to the literature dealing specifically

with the individual species as well as the taxonomic group have

been included in each guide to provide additional information fUr

anyone requiring more detailed information. Furthermore, discus-

sions of taxonomic methods, terminology and discussions in depth

on individual species are provided whenever possible.

During the preparation of these guides, established interna-

tional specialists in the different taxonomic groups have been

4

called upon for comment and advice whenever it was required. We

would like to express our gratitude to the following colleagues

for their helpful advice.

The guides were subjected to rigorous evaluation tests in

which the principal criteria were accuracy and degree of ease in

establishing the identification of the organism. This work has

required, not only the examination of hundreth of samples taken

throughout the years, but also comprehensive review of the liter-

ature of the Arctic fauna as far back as the late 18th century.

The responsibility for coordination and editorial work in

the production of the guides was given to Ms. Hester Kobayashi.

Zooplankton Sorting Program

Sampling Method

Sorted under this program were samples collected from Ice

Island, T-3, with 1 meter diameter, 215 micrometer mesh, closing

nets towed vertically at a uniform rate of 20 meters per minute.

Samples were collected from March 1970 to September 1970 by

Mr. John Dawson and Mr. Lloyd Ellis, of USC, and from December

1970 to January 1972 by members of the University of Washington

T-3 Program under Dr. T. S. English.

The following sampling protocol was used:

tiarch-Sept. 1970 December 1970-Jan. 1972

Sample Processing

The preliminary processing of the collected samples was done

under the direction of Mr. John Dawson. Undergraduates were

trained to recognize the major groups of zooplankton prominent in

the Arctic water column. This function has involved eight under-

graduates partially supported under the Federal College Work Study

Program.

With the help of these student assistants, samples were com-

pletely separated into the following general taxonomic groups and

and the numbers of the specimens recorded'

The identification of animals to genera and species, only a

small portion of which is complete, has been handled by specialists

in the USC group. The data have been recorded in special tabulation

sheets and arranged for easy retrieval for computer treatment in the

future. -All samples and data are stored in the Hancock Foundation

of the University of Southern California. Ta',les I-XIII summarize

Results of the Sorting Program

The sorting program had two principal objectives. First, it

was designed to provide additional information of the faunal

content of the central Arctic Basin and thereby enable'us to

produce more complete and accurate taxonomic guides. Second,

through the systematic collection at discrete depths with closing

nets over a two year period, it was possible to accumulate a

wealth of synoptic information on the distribution of zooplankton

in time and space over a long period of time. Analysis of this

information has now yielded a large amount of information on ver-

tical migrations and life cycles. This information in turn allow-

ed us to select those key species which can serve as models in

studying vertical migrations of zooplankton populations as well as

those interactjins between organisms and the environment which

play an important role in the formation and behavior of sonar

scattering layers of biological origin. The studies which already

have been completed are summarized below.

Vertical Distribution and Life History of the AnnelidPelogobia longicirrata

Pelagobia longicirrata is the most common pelagic polychaetein the central Arctic Basin. It is a cosmopolitan species whichis found not only in the Arctic but in deep waters of other oceansas well. Since very little is known about the biology of pelagicpolychaetes it was decided to analyse the presence of Pelagobiain our plankton samples in order to study its vertical distribu-tion and life cycle.

The results indicate that the majority of the animals arelocated between 300 and 500 meters throughout most of the year.The specimens found in this depth range are primarily breedingadults over 13 segments in size. In the spring and summer, the

9

percentage of animals which are found below 500 meters increases.Ho-." er, most animals found below 500 meters tend to be less than13 segments in size with the smallest specimens usually associatedwith the greatest depths. It was also found that 'he period ofthe year during which the percentage of animals increases below500 meters is closely correlated with the breeding season. Ourobservations suggest that adults spawn between 300 and 500 metersin the spring and that the eggs or larvae, or both descend todepths below 1000 meters. Then as the larvae develop they ascendgradually.

This study was carried out by Mr. Douglas Yingst.

The Growth Cycle and Related Vertical Distributionof the Pteropod, Spiratella helicina,

in the Central Arctic Ocean-- The mechanisms which give rise to aggregations of plankton

communities in the water column are not well understood. However,it is known that a number of factors both of environmental andbiological origins can influence the formation and behavior ofthese aggregations. As an approach to this problem the pteropodS. helicina was selected as a model organism because of itspresence in the 50 meter scattering layer in the Arctic, its re-lative abundance, dependence upon particulate material for food,and ease in recognition. Here we report on a study of its growthcycle and verticAl distribution.

The growth and reproductive cycle of S. helicina in the cen-tral Arctic Ocean was studied by examining samples collected fromalong the drift paths of ice stations ARLIS I, II, and T-3. Shelldiameters were measured, and gonadal development examined by his-tological means. Vertical distribution in the water column wasalso investigated.

S. helicina has an annual life cycle; spawning occurs mainlyduring the spring and summer months and the oldest animals dieby March. Maturation of young into males occurs as the animalsreach about 0.7 mm diamete2 (February-April) and to hermaphroditesby the time they reach about 0.8 mm (May). The young double their

size during the months of October to January. This growth rateslows down at the time of sexual maturation and through the majorspawning period but picks up again during the fall and winter.Growth and maturation during the winter months suggests that somefood must be available to S. helicina during the dark period ofthe year when phytoplankton is least available.

The analysis of the vertical distribution indicates thatthe youngest juvenile forms tend to remain predominantly in the first

f

10

50 meters interval of the water column (0.2 mm to 0.4 mm), there-after remaining within the first 100 meters until maturation.Animals larger than 0.9 mm seem to be dispersed in the water columnduring the peak period of primary productivity and concentratedin the top 100 m when food is less abundant.

This study was carried out by Ms. Hester Kobayashi.

Taxonomy and Distribution of the Arctic Speciesof Lucicutia (Copepoda: Calanoida)

Analysis of approximately 400 plankton hauls from the ArcticOcean revealed the presence of Lucicutia polaris Brodsky, L.pseudopolaris Heptner, and L. anomala Brodsky in samples collec-ted in deep waters. The two former species are closely relatedbut differ in morphological and biolegical characteristics of theadults and juvenile stages. The male of L. anomala is describedfor the first time. These species have a wide geographical dis-tribution in the Arctic Ocean. They inhabit the Arctic bottomwater and show different but overlapping ranges of vertical dis-tribution. L. pseudopolaris is most abundant at a deptb of about1500 m; L. polaris preferentially lives at a depth of about 2000m; and L. anomala is found in waters deeper than 2000 m but ismost abundant at depths exceeding 3000 m.

This study was performed by Mr. Julio Vidal and recentlyappeared in the Bull. So. Calif. Academy of Sciences. 70(l):23-30,1971.

On the Ostracod Fauna of the Arctic Basin

This study involved the analysis of plankton and undericecollections from drift stations ARLIS I, ARLIS II and T-3. Fivespecies of ostracods have been identified, among which, one isnew to science and one is a new record in the Arctic Ocean.

Conchoecia borealis maxima is the predominant species in theBasin and is found in collections from the first 1500 meters ofthe water column.

Conchoecia elegans is found together with C. borealis maximain collections from the first 750 meters. The Arctic specimensappear larger than those collected at lower latitudes in theAtlantic. On the basis of the variation in sizes, it appears thata taxonomic revision should be considered.

Conchoecia skogsbergi, the 'long form' of the C. rotundagroup, is very common in the Antarctic and north Atlantic, but isa new record in the Arctic. This species is similar to the speciesdescribed by Angel (1968) but the present form is larger. Recent

investigation shows that this species also varies considerably insize at different latitudes, thus requires taxonomic revision too.

A female of a new species of Bathyconchoecia has been collec-ted and is still under study.

Acetabulastoma arcticum, earlier described by Baker and Wong(1968) as Paradoxostoma rostratum, is a paras..tic form which in-fests the amphipods, Gammarus wilkitzkii and Gammaracanthusloricatua. Although other species of Sammarids have been examined,these are the only two species infested by Acetabulastoma.

I Mr. Yuk maan Leung was assigned to study the ostr;ods.

Annual Vertical Distribution of Calanus hyperbgreusin the Central Arctic Ocean

Calanus hyperboreus is the largest and one of the most abun-dant copepods in the central Arctic Basin. We have carried outa study of the biology of this copepod with special emphasis onvertical distribution of copepodite stages II through V and ofthe adult males and females over a two year period.

During the molting sequence from copepodite stage II to adultform, the most rapid growth occurs during July, presumably coin-ciding with the phytoplankton bloom. Our study of the verticaldistribution patterns of the different stages suggest that thereare three different types. Copepodite stages II to V show onetype which is characterized by an undulating annual vertical mi-gration. For example the maximum concentration of stages II-Vcopepodites occurs at depths between 300 and 500 meters in winter.During the spring there is a gradual migration towards the surface.At the end of the summer they descend once again gradually to re-main at depths of 300 to 500 meters during winter.

Adult females are mainly found at depths of 100 meters in thespring, and as the season progresses they appear to descend at a.rate of 50 meters per month. However during the summer they arefound everywhere from the surface to a depth of 300 meters. Itis thought that the females which migrate downwards in the springremained there and that those found at the surface are newly moltedfemales. In the fall the population centered at 150 meters. ByDecember, however, they are distributed from near the surface to450 meters. It is possible that those adult females which wereconcentrated in the fall at 150 meters remained near the surfaceduring December, and those females found at greater depths arethe result of molting from stage V coppoc.ites which are found indeep water in December.

12

The vertical distribution of adult males centers between 400_and 800 meters and therefore is generally deeper than that of thefemales. They also differ in that they are only present duringthe spring and early summer. It is at this time when we foundup. tO 30% of the females gravid.

Careful analysis of the life span of the various stagessuggests that in the Arctic Basin C. -hperboreus has a generationlength of about three years.

This work was carried out by Mr. John Dawson.
