Aiming to develop the biological resources of the Okhotsk Sea shelf zone, a remote study of regional features of the ice processes dynamics in fishing areas is important. One of the main fishing areas of the Okhotsk Sea is the West Kamchatka subzone — the northeastern sector of the water area to the east of 153°30′ E, bounded from the south by latitude 54° N. Dynamics of seasonal changes in ice cover is inherent in every region of the sea, regardless of the total area of ice. Geophysical processes affect the ice cover through a complicated mediated correlation that includes changes of the atmospheric circulation parameters. Critical, anomalous states of the ice cover in the West Kamchatka fishing subzone and also the cause-effect relations of its formation are revealed during the pollock seasons in 2006–2017. The mechanism of influence of thermobaric conditions, confirming the influence of the Okhotsk tropospheric cyclone (OTC) and the Pacific tropospheric crest on the formation of abnormal ice conditions in the Okhotsk Sea both in general and in certain local areas is presented.

Coconuts provided commodities for the West in the form of coconut oil and copra. Once colonial governments established control of the tropical Pacific Islands, they needed revenue so urged European settlers to establish coconut plantations. For some decades most copra came from Indigenous growers. Administrations constantly urged the people to thin old groves and plant new ones like plantations, in grid patterns, regularly spaced and weeded. Local growers were instructed to collect all fallen coconuts for copra from their groves. For half a century, the administrations’ requirements met with Indigenous passive resistance. This paper examines the underlying reasons for this, elucidating Indigenous ecological and social values, based on experiential knowledge, knowledge that clashed with Western scientific values.

AbstractNot everything that is logically possible and technically feasible is also natural, for example, placing China in the exact center of a world map. Such a map would not correspond to the laws of perception.Matteo Ricci, who was the first to create Chinese world maps on which the Americas were depicted, had to choose between two ideals, between a world map that obeys the gestalt principles of perception and a world map with the “Central State” China in its center. The first ideal mattered more to him than the second, although he took the latter into account as well. The result was a Pacific-centered map.Since we live on a sphere, what we perceive to be in the East and in the West depends on our location. It is therefore natural that in East Asia, world maps show America in the East and not – as in Europe – in the West. This was the argument underlying Ricci’s creation of Pacific-centered maps, and not the intention of depicting China as close to the center of the map as possible.It is only in East Asia that Ricci was the first to create Pacific-centered maps. World maps with the Pacific in the midfield were made in Europe before Ricci, motivated by the traditional unidirectional numbering of the meridians (0°–360°) from West to East starting with the Atlantic Insulae Fortunatae (Canary Islands).

AbstractThe northeastern Pacific Ocean is a preferential location for the formation of closed low pressure systems. These slow-moving, quasi-barotropic systems influence vertical stability and sustain a moist environment, giving them the potential to produce or affect sustained precipitation episodes along the west coast of the United States. They can remain motionless or change direction and speed more than once and thus often pose difficult forecast challenges. This study creates an objective climatological description of 500-hPa closed lows to assess their impacts on precipitation in the western United States and to explore interannual variability and preferred tracks. Geopotential height at 500 hPa from the NCEP–NCAR global reanalysis dataset was used at 6-h and 2.5° × 2.5° resolution for the period 1948–2011. Closed lows displayed seasonality and preferential durations. Time series for seasonal and annual event counts were found to exhibit strong interannual variability. Composites of the tracks of landfalling closed lows revealed preferential tracks as the features move inland over the western United States. Correlations of seasonal event totals for closed lows with ENSO indices, the Pacific decadal oscillation (PDO), and the Pacific–North American (PNA) pattern suggested an above-average number of events during the warm phase of ENSO and positive PDO and PNA phases. Precipitation at 30 U.S. Cooperative Observer stations was attributed to closed-low events, suggesting 20%–60% of annual precipitation along the West Coast may be associated with closed lows.

Prevelar raising and fronting has been documented as a “defining feature” of Pacific Northwest English yet its status nearby in California remains unclear. This paper investigates prevelar raising/fronting across four Californian field sites. Examining wordlist data from 276 white speakers, and sociolinguistic interview data from 64 white speakers, the current study shows that - contrary to previous assumptions - prevelar conditioning is not confined to the Pacific Northwest, but extensive throughout California. Results suggest that, in line with previous work in Washington and Oregon, this prevelar pattern is also on the decline among younger Californians, although the trajectory of change appears to differ from that observed in Washington (e.g. Riebold 2015). This paper complicates the notion of prevelar tensing, showing that F1 and F2 are not always operating in tandem: speakers who raise BAG, for example, do not always front BAG to the same degree, and vice versa. As this is yet more evidence that the West is broadly participating in similar vocalic patterns, this study tentatively explores historical migration events as one possible source for the contemporary Western vowel system.

Ice Regime

The ice regime of rivers is considered a sensitive indicator of climate change. This paper summarises the results of research on the long-term changes in the ice regime parameters under changing climate conditions and their regional peculiarities in Latvia from 1945 to 2012. The ice cover duration on Latvian rivers has decreased during recent decades. The research results demonstrated that there is a positive trend as regards the formation of the ice cover and in 31.8% of the cases the trend is statistically significant at p < 0.05. As regards the breaking up of ice, there is a statistically significant negative trend in 93.2% of the cases at p < 0.05. This indicates an earlier ice break-up date, which in turn, displays a strong correlation with the increase of the air temperature. The same pattern applies to the reduction of the length of ice cover (a statistically significant trend in 86.4% of the cases at p < 0.05). In approximately 60% of the cases, there is a statistically significant reduction of the ice thickness. The estimated winter severity index indicates warmer winters over the last 20 years as well as regional differences in the west–east direction.
