NO. 9 MARINE INVERTEBRATES, ALASKA — MacGINITIE 95 



8- 3-49 Morning : Surf heavier again. Water murky. No animals seen along- 

 shore. 

 Evening: Heavy swells. Water churning. One amphipod collected. 

 8- 4-49 Morning: Light surf. Water clear. No animals seen. 



Evening: Medium light surf. Water clear. No animals seen. 

 8- S-49 Evening: Medium light surf (9 p.m.). Water clear. Capelin observed 

 flipping out of the water about 20 feet from shore. By 9 :45 they 

 were close enough to the shore to catch them with a hand net. By 

 10 p.m. large numbers of gulls were seen on and about the water 

 from near the village to the base. 

 8- 6-49 Morning: Water clear. No animals seen. 



Evening: Medium heavy surf. Water clear. A few amphipods ob- 

 served on the beach above the breaking surf, 

 8-1 1-49 Heavy surf. No animals visible from the shore. A few jellyfishes, 

 to Cyanea capillata, were washed ashore. 



8-15-49 



8-17-49 Water fairly calm. Hundreds of small Cyanea capillata in water 

 offshore, Halistaura ccllularia common but less abundant than above 

 species, and small medusae were visible. 



8-19-49 Water fairly calm. Small Cyanea seen near the Point, 



8-21-49 Very heavy surf. A 25-mile northeast wind. A few animals, such as 

 Arenicola glacialis and Antinoe sarsi, and several amphipods, 

 Monoctilodes horealis, M. schncideri, Gammarus locustus var. 

 setosus, Weyprechtia heuglini, Melita formosa, Protomedcia fas- 

 cia ta, and P. stephenseni, n. sp., were on the beach. 



8-22-49 Very high surf alongshore. It cut the beach back 40 feet and the 

 boat had to be moved farther back on shore. 



8-23-49 Since 8-21-49 a series of spits have been moving along the beach 

 toward the southwest, forming eight projecting lobes in a distance 

 of about 1.5 miles. The lobe near the boat moved down the beach, 

 that is, southwest, a distance of 190 feet and the extension into the 

 sea is 75 feet from the normal shoreline. The movement of these 

 lobes or scallops is easily accounted for — the breakers have been 

 curling against the beach at an angle of about 60 degrees from the 

 perpendicular to the beach line. 



8-24-49 Still very stormy. High wind and fairly heavy surf. Colder air. 

 Wind in the same direction for four days. The storm washed 

 various animals ashore, chief among which were amphipods. These 

 formed a continuous line along the beach where they were left by 

 the surf: 



Lafoeina maxima 2 colonies 



Burrowing anemone i 



Arenicola glacialis Common 



Antinoe sarsi Few 



Melaenis loveni Few 



Cumacean i 



Hyperia medusarum i 



Themisto libellula 2 young females 



Onisimus affinis i female with embryos 



Acanthostepheia behringiensis 4 females, 5 males, 2 immature females
