INTRODUCTION . . .A Brief History

For anyone interested in studying the marine algae of Alaska, the lack of a single reference work to the flora of the area is an immediate and almost over- whelming handicap. This volume attempts to fill that void on an interim basis by providing within one cover references to all of the published and some of the unpublished work on the seaweeds of this area.

Records of seaweed collections in Alaska before the turn of the century are described by Setchell and Gardner (1903). Their account of these early collections is utilized in the following narrative. Papenfuss (in Abbott and Hollenberg, 1976) also provides a very readable phycological history of Pacific .

The first collection made in the vicinity of Alaska was by Steller, who visited the shores of Kamchatka between 1742 and 1745. Algae collected by him were described by Gmelin in 1768. The first algae collected in the area popularly known as the Pacific Northwest were taken by Menzies, who visited this area in a trading ship between 1779 and 1786 and later accompanied Vancouver on his exploratory voyages in the Northwest, including Alaska, between April 1791 and October 1795. Menzies' collections were figured and described by Turner in publications which appeared between 1808 and 1819. Several collected by Menzies were named and imperfectly described by Esper in 1802 from fragments sent him by Turner without the latter's suspicion of how they were to be used.

Chamisso collected many algal specimens on Von Kotzebue's expedition between 1816 and 1817, which included a stop at Unalaska, and these specimens were described chiefly by C . Agardh in 1821 and 1822.

In 1826 to 1829, Postels and Mertens accompanied Lutke to the Northwest coast. Mertens made notes, some of which were published in 1829. Postels made a series of magnificent drawings which were later published with Ruprecht in 1840. Kastalsky, on another of Lutke's ships, also collected material which was utilized by Postels and Ruprecht in their Illustrationes Algarum. Collections were made at Sitka, the Alaska Peninsula, Unalaska, the , and Kamchatka . One of the most valuable phycology references to Alaska and the Northwest coast came from a 1851 publication by Ruprecht on collections made in the Sea of Okhotsk by Redovski as well as by M~osnessenskiand Middendorf and also by Steller. Although dealing with another area, this work contains valuable references to species and specimens from Alaska and the Northwest with notes on their occur- rence there and comparisons with similar or identical species from other areas.

In 1889, Kjellman enumerated the algae collected during Nordenskjold's voyage in 1880 through the Bering Strait to Port Clarence and St. Lawrence Island. In 1899, Setchell brought together and published records of algae collected in the Pribilof Islands by a variety of people.

Many of the records of Alaska algae from the 1903 paper by Setchell and Gardner came from an extensive collecting trip made in 1899 by the University of and including Jepson, Hunt, Lawson, and Setchell . This group collected at St. Michael, Cape Nome, Unalaska Bay, Delarof Harbor on Unga Island, Karluk, Uyak Bay, St. Paul (Kodiak Island) , Orca, Juneau, and Sitka. Setchell and Gardner also utilized collections made by private individuals and commercial com- panies in Alaska that had been deposited in the University of California herbarium. These collections came from various areas in the territory, including the eastern , St. Paul Island, , Morzhovoi Bay, and Islands in the Aleutians, Yakutat Bay and Sitka.

In June and July of 1899, the Harriman expedition also visited Alaska. Marine algae were collected at Annette Island, Wrangell, Juneau, Sitka, Glacier Bay, Prince William Sound (near Orca and in Virgin Bay), Cook Inlet, Kukak Bay, Kodiak Island, and Popof and Unga Islands in the Shumagin group. These specimens were identified by Saunders, who was also a member of the expedition, in 1901.

Between 1913 and 1915, the U . S . Bureau of Soils sent two expeditions to Alaska to assess the availability of commercial quantities of the Alaria fistulosa , Macrocystis integrifolia , and Nereocystis luetkeana . Reports of these two expeditions were written by Frye (1915) and Rigg (1915).

Several collections by Japanese phycologists have also been made in Alaska (Okamura, 1933; Tatewake and Kobayashi, 1934; Chihara, 1967) .

Collections made during the summers of 1959-1960, 1962-1966, and 1968-1969 under the direction of Dr. Robert F . Scagel of the University of British Columbia have included both intertidal and subtidal sites in Alaska from Dixon Entrance to the Gulf of Alaska, including Kodiak Island, and through the inner as far as . Publications from these collections are currently limited to papers on and the distribution of the Laminariales by Druehl (1968, 1970) and on Hedophyllum and Alaria by Widdowson (1965, 1971), and a paper on Porphyra by Conway, Mumford, and Scagel (1975). Another collecting trip sponsored by the University of British Columbia was made to Southeastern Alaska in January 1971. Markham, McBride, and Newroth (1972) report on the species collected during that voyage. Following the Good Friday earthquake in 1964, the National Academy of Sciences sponsored a biological expedition to Prince William Sound in the late spring and early summer of 1965. Algal specimens from the 33 stations were collected and identified by Johansen and reported in 1971.

A biological assessment program preceding and following the two atomic bomb tests on Island provided extensive information on seaweed distri- butions and biological interactions on this island between 1967 and 1973 (Burgner, --et al., 1968, 1969, 1971a, 1971b, 1972; Dayton, 1975; Estes, 1974; Estes and Palmisano, 1974; Lebednik, 1973; Lebednik and Tutmark, 1970; Lebednik, et-- al., 1971; Nakatani, --et al., 1973, 1974; Palmisano, 1975; Weinmann, 1969; Wynne, 1969, 1970a, 1970b, 1971a, 1971b) . Lebednik (personal communication) has collected seaweeds in Alaska both under the auspices of the Amchitka program and on his own.

Results of a seaweed survey made by the University of Alaska in northern Southeastern Alaska and on the north side of the Alaska Peninsula in 1970 were published the following year (McRoy, --et al., 1971). The university has also been involved in other surveys, most of which remain unpublished, including an intertidal survey for the National Park Service in Glacier Bay in 1971-72 (Mueller , 1973) . Collections have also been made in Valdez Arm in relation to future oil tanker traffic.

The Auke Bay Fisheries Laboratory of the National Marine Fisheries Service has also been involved in seaweed collections in Alaska in recent years. Collec- tions were made in Valdez Arm between 1972 and 1975. Collections in the Gulf of Alaska began in the fall of 1974 and have included sites, from east to west, at Ocean Cape (near Yakutat) , Cape Yakataga, Kayak Island, Katalla, Boswell Bay, Port Etches, Zaikof Bay, Middleton Island, MacLeod Harbor, Day Harbor, Port Dick, Sud Island (Barren Islands), Cape Nukshak, Three Saints Bay, Sundstrom Island (Trinity Islands) , Chirikof Island, and Spectacle Island (Shumagin Islands) . Collections in the Bering Sea were begun in 1975 and have included Crooked Island (), Point Edward (near Port Moller), Cape Pierce, , Cape Mordvinof , , Makushin Bay () , St. George Island, and (Zimmerman and Merrell , 1975) . Subtidal collections have also been made at several of the sites.

A few collections have been made by Dames and Moore of Anchorage, including Kachemak Bay (ADF&G collection--Homer, Alaska) and the Gulf of Alaska (Flagg, 1975) .

CONTENT OF BIBLIOGRAPHY

This volume is divided into three sections. The systematic list (pages 5-17) includes the taxonomic hierarchies to which the green (Chlorophyta), brown (Phaeophyta) , and red (Rhodophyta) algae of Alaska belong. The species bibli- ographies (pages 18-157) include information on the distribution of each species from Alaska south along the Pacific coast of North America, its habitat, and records of its occurrences in Alaskan waters . The literature bibliography section (pages 158-165) includes references cited in the species bibliographies and other references to marine algae in Alaska. A total of 376 species in 169 genera are includec in this bibliography. Of this total, 58 species are green algae, 107 species are , and 211 species are .

The author relied strictly on available literature and personal communi- cations to determine which species have been reported from Alaska and to ascer- tain their current taxonomic status. Personal observations were used to indicate the doubtfulness of several recorded distributions. No herbarium material was examined with the exception of specimens from the Auke Bay Fisheries Laboratory collection (ABFL) , the Alaska Department of Fish and Game collection in Homer, and the author's personal collection (SCL) . Unless otherwise specified, material from these herbaria was collected and identified by the author.

For locations of specific geographic places, the reader is referred to the original literature or to the Dictionary of Alaska Place Names, Geographical Survey Professional Paper 567, U .S . Government Printing Office, 1967.

The concept for this bibliography came from the invaluable usefulness of Dr. Robert F. Scagel's "An Annotated List of the Marine Algae of British Columbia and Northern Washington." I have borrowed heavily from the species distribution records and the habitat descriptions of his volume. His introductory remarks also seem particularly appropriate to the present work, and I would like to borrow from them as well:

If one waited until any one phase of scientific investigation were completed to the satisfaction of everyone before publishing a paper, little progress would be made, and libraries would be barren of volumes to which one could turn for advice, guidance, and exchange of ideas. The person least satisfied with a paper when it appears in print is usually the author--certainly no one is more aware of its shortcomings. In this respect this paper is by no means an exception. The only excuse for its presentation is that it may serve as a starting- point from which further knowledge of the marine algae in this relatively little-known area may develop. It is hoped that the effort which has gone into the preparation of the paper will succeed in stimulating others in this region to develop an interest in marine phycology. Only by arousing such an interest will it be possible to further increase our knowledge of the marine algae. If this objective is reached, then the publication of this paper will be justified and no further apology will be required for presenting it with its possible errors, omissions, and obvious limitations .
