AbstractArctic sea ice is rapidly decreasing during the recent period of global warming. One of the significant factors of the Arctic sea ice loss is oceanic heat transport from lower latitudes. For months of sea ice formation, the variations in the sea surface temperature over the Pacific Arctic region were highly correlated with the Pacific Decadal Oscillation (PDO). However, the seasonal sea surface temperatures recorded their highest values in autumn 2018 when the PDO index was neutral. It is shown that the anomalous warm seawater was a rapid ocean response to the southerly winds associated with episodic atmospheric blocking over the Bering Sea in September 2018. This warm seawater was directly observed by the R/V Mirai Arctic Expedition in November 2018 to significantly delay the southward sea ice advance. If the atmospheric blocking forms during the PDO positive phase in the future, the annual maximum Arctic sea ice extent could be dramatically reduced.

Recent examinations of cucullanid nematodes (Cucullanidae) from marine fishes off New Caledonia, collected in the years 2004–2009, revealed the presence of the following five new species of Cucullanus Müller, 1777, all parasitic in Perciformes: Cucullanus variolae n. sp. from Variola louti (type host) and V. albimarginata (both Serranidae); Cucullanus acutospiculatus n. sp. from Caesio cuning (Caesionidae); Cucullanus diagrammae n. sp. from Diagramma pictum (Haemulidae); Cucullanus parapercidis n. sp. from Parapercis xanthozona (type host) and P. hexophtalma (both Pinguipedidae); and Cucullanus petterae n. sp. from Epinephelus merra (type host) and E. fasciatus (both Serranidae). An additional congeneric species, Cucullanus bioccai Orecchia et Paggi, 1987 was recorded from Mugil cephalus (Mugilidae, Mugiliformes) (first record in the Pacific Ocean) and Cucullanus sp. (only female) was found in Arothron manilensis (Tetraodontidae, Tetraodontiformes). Furthermore, two known cucullanid species, Dichelyne (Cucullanellus) branchiostegi (Yamaguti, 1941) in Branchiostegus wardi (Malacanthidae, Perciformes) (new host and geographical records) and Dichelyne (Cucullanellus) bodiani Moravec et Justine, 2019 in Bodianus busellatus (new host) and B. perditio (both Labridae, Perciformes), were found; Dichelyne (Cucullanellus) sp. (only females) coinfecting the latter host may represent an unknown species. Most species are described based on light and electron microscopical studies. The specimens described by Xu et al., 2017 as Cucullanus bourdini Petter et Le Bel, 1992 from Caesio xanthonota (Caesionidae) in the Taiwan Strait are considered to represent a new species, for which the name Cucullanus sinensis n. sp. is proposed.

The generic diagnoses of Bacciger and Pentagramma are emended. Recognized as members of the genus Bacciger are the type, B. bacciger (Rudolphi, 1819), from the Mediterranean, Black, and Azov Seas; B. nicolli Palombi, 1934, from Atlantic waters near the British Isles; and B. opisthonemae Nahhas and Cable, 1964, from Jamaican waters. Pentagramma consist of P. symmetricum Chnlkova, 1939, the type, from the Black and Azov Seas and P. petrowi (Layman, 1930) n. comb, from the northern part of the North Pacific region. Synonyms of P. petrowi are Monorcheides(?) petrowi Layman, 1930: Orientophorus sayori Yamaguti, 1942; Faustula sayori (Yamaguti, 1942); Orientophorus petrowi (Layman, 1930); and Bacciger petrowi (Layman, 1930). Pentagramma petrowi is redescribed and additional details of morphology are included for P. symmetricum, B. bacciger, and B. nicolli. Measurements of the species discussed and extensive host and locality records are tabulated.
