Observations by the Ulysses SWOOPS plasma experiment are used to investigate spatial and temporal gradients during the mission, with emphasis on more recent high latitude observations including the recent South Pole to North Pole passage during solar minimum. Compared to lower latitudes, the high latitude solar wind had higher average speed, proton temperature, and momentum flux, and lower numb...

The prevalence of winter SAD was measured in two groups of a(lult Manitobans of wholly Icelandic (lescent, 210 resident in Winnipeg (50 degrees N) and 252 resident in the nearby Interlake district (50.5 degrees N), using the Seasonal Pattern Assessment Questionnaire (SPAQ). These groups live practically at the same latitude and are according to all indications genetically identical. The age-and...

Research, monitoring and management of large marine protected areas require detailed and up-to-date habitat maps. Ningaloo Marine Park (including the Muiron Islands) in north-western Australia (stretching across three degrees of latitude) was mapped to 20 m depth using HyMap airborne hyperspectral imagery (125 bands) at 3.5 m resolution across the 762 km(2) of reef environment between the shore...

In documenting biological responses to climate change, the Intergovernmental Panel on Climate Change has used phenology studies from many parts of the world, but data from the high latitudes of North America are missing. In the present article, we evaluate climate trends and the corresponding changes in sequential bloom times for seven plant species in the central parklands of Alberta, Canada (...

Leaf reflectance at visible and near-infrared wavelengths (400-1000 nm) is related primarily to pigmentation, leaf structure and water content, and is an important tool for studying stress physiology and relationships between plants and their growth environment. We studied reflectance of two co-occurring Alaskan conifers, black spruce (Picea mariana (Mill.) BSP) and white spruce (Picea glauca (...

positive correlation at 65 +/5 degrees N geomagnetic latitude and altitudes 44-58 km in Figure 5. I am wondering about any possible significance of the large negative correlation, which is computed for 35 +/5 degrees S geomagnetic latitude and altitudes 50-62 km in Figure 5. Could the authors please elaborate on this as well? The mechanism for this is not yeat clear, but this is out of the scop...

Galactic supernova remnants (SNRs) with angular dimensions greater than a few degrees are relatively rare, as located more ten off the plane. Here we report UV and optical investigation of two previously suspected SNRs in both diameter latitude. One is proposed remnant discovered 2008 through 1420 MHz polarization maps near coordinates $l$ = 353, $b$ $-$34. GALEX far (FUV) H$\alpha$ emission mo...

We investigated physiological traits responsible for determining the tide-height and latitudinal distributions of Northeastern Pacific Nucella congeners. First, we determined the thermotolerances of two species of intertidal dogwhelks, N. ostrina and N. canaliculata, which co-occur on the Oregon coast. We found that N. ostrina, which are distributed higher on the shore, and thus experience high...

The Municipality of Anchorage (MOA), at 61 degrees north latitude, ploughs and hauls snow from urban streets throughout the winter, incorporating grit and chloride applied to street surfaces for traffic safety. Hauled snow is stored at snow disposal facilities, where it melts at ambient spring temperatures. MOA studies performed from 1998 through 2001 show that disposal site melt processes can ...
