(Tables 1, 3) Details of Agassiz trawl stations and numbers of specimens per macro- and megazoobenthic taxon collected during POLARSTERN cruise ANT-XXII/3 (ANDEEP III)

The assemblages inhabiting the continental shelf around Antarctica are known to be very patchy, in large part due to deep iceberg impacts. The present study shows that richness and abundance of much deeper benthos, at slope and abyssal depths, also vary greatly in the Southern and South Atlantic oceans. On the ANDEEP III expedition, we deployed 16 Agassiz trawls to sample the zoobenthos at depths from 1055 to 4930 m across the northern Weddell Sea and two South Atlantic basins. A total of 5933 specimens, belonging to 44 higher taxonomic groups, were collected. Overall the most frequent taxa were Ophiuroidea, Bivalvia, Polychaeta and Asteroidea, and the most abundant taxa were Malacostraca, Polychaeta and Bivalvia. Species richness per station varied from 6 to 148. The taxonomic composition of assemblages, based on relative taxon richness, varied considerably between sites but showed no relation to depth. The former three most abundant taxa accounted for 10-30% each of all taxa present. Standardised abundances based on trawl catches varied between 1 and 252 individuals per 1000 m2. Abundance significantly decreased with increasing depth, and assemblages showed high patchiness in their distribution. Cluster analysis based on relative abundance showed changes of community structure that were not linked to depth, area, sediment grain size or temperature. Generally abundances of zoobenthos in the abyssal Weddell Sea are lower than shelf abundances by several orders of magnitude.

Lt. Col. John Clark Papers, 1838-1851 [photocopy]

Lt. Col. John Clark (1787-1862) was born in Kingston, Upper Canada. In 1801 Clark became a private in the 1st regiment of the Lincoln Militia, serving under Ralfe Clench. By June 1812 he was promoted to lieutenant by Maj. Gen. Sir Isaac Brock. During the War of 1812 he served as lieutenant and adjutant for the Lincoln Militia flank company on the Niagara frontier under Col. William Claus, and was present at the surrender of the enemy at the battle of Queenston Heights. By 1838 the Lincoln Militia was being re-organized and Lt. Col John Clark was requested to lead the 5th Regiment, made up of men from both Grantham and Louth townships in Lincoln County. He served in this capacity until his retirement in 1851?. Around this same time Clark bought from William May Jr. a house in Grantham Township. He was to call his home Walnut Dale Farm. John Clark also served as the customs collector for Port Dalhousie, and as a secretary in the Welland Canal Company. One hundred years later efforts by a local heritage group to save John Clark’s home failed, when the house was hit by arsonists. By this time the house had become known as the May-Clark-Seiler House. See RG 195 Anne Taylor Fonds for more information regarding the efforts of the heritage group to save this home. Clark died in 1862 at the age of 79 years and is buried in Victoria Lawn Cemetery. John Clark’s daughter Catherine (mentioned in the diary portion of the papers) was married to William Morgan Eccles.

Taxonomic review of Haliclystus antarcticus Pfeffer, 1889 (Stauromedusae, Staurozoa, Cnidaria), with remarks on the genus Haliclystus Clark, 1863

Difficulties concerning the taxonomy of stauromedusae are long known, and there is a clear need for taxonomic revision of the genus Haliclystus, as well as the reevaluation of some species. Haliclystus antarcticus Pfeffer, 1889 is recorded from Admiralty Bay, King George Island, Antarctic Peninsula. Due to the lack of detailed information on this species, we provide a redescription, presenting new data on the cnidome, morphometry, geographical distribution and intraspecific variation. Based on these characters, we propose that our specimens and Haliclystus auricula from Chile and Argentina are synonymous and should be classified as H. antarcticus. We also review the worldwide distribution of the genus Haliclystus Clark, 1863 and discuss taxonomic issues, concluding that some characters traditionally used in the taxonomy of the group should be used cautiously.
