Seasonal variation in the Chironomidae (Diptera) communities of two Faroese streams

open access: yesCHIRONOMUS Journal of Chironomidae Research, 2023
Seasonal variation of freshwater invertebrate communities is strongly influenced by abiotic factors including temperature and precipitation which, in turn, are predicted to be affected by climate change. It is important to study these effects, not least

A simplified model to predict diurnal water temperature dynamics in a shallow tropical water pool [PDF]

open access: yes, 2008
Water temperature is a critical regulator in the growth and development of malaria mosquito immatures, as they are poikilothermic. Measuring or estimating the diurnal temperature ranges to which these immatures are exposed is of the utmost importance, as

Observations of Snow Accumulation and Sea Ice at Syowa Station, Antarctica

open access: yesAntarctic Record, 1971
第8次(1967年),第9次(1968年),第10次南極地域観測隊(1969年)において実施された昭和基地周辺の海氷上(北の浦およびオングル海峡)における,積雪量と海氷厚の観測結果をまとめて報告する。北の浦海氷上における積雪量は,場所による大きな相違があるが,おおむね卓越風向の風上地域では非常に少なく,風下の東オングル島に近い地域では多いという傾向が見られた。最も積雪量の多い所では,積雪深が9月から10月頃に120cmを越え,最も少ない所では,年間を通してほとんど積雪がなかった。北の浦全域の平均積雪深は,
