Summary
DescriptionLinnuradarid linnutee rändureid seiramas.jpg |
Eesti: Moodsad linnuradarid (vasakul horisontaal- ning paremal vertikaalradar) võimaldavad jälgida lindude rännet ka ööpimeduses, mil klassikalised vaatlused pole võimalikud. Radaruuringud lubavad saada teavet lindude rändeaktiivsuse, selle fenoloogia, kõrguse ja seoste kohta keskkonnatingimustega.
Radarseirega on leidnud kinnitust asjaolu, et lindude öine ränne on aktiivseim tähistaevaga ning on selgunud, et ligikaudu pool kogurändest leiab aset öötundidel. Pildil olevate radaritega seiratakse lindude rännet Tartu Ülikooli Eesti Mereinstituudi välibaasis Kihnus, Eesti Energia AS tellimusel, et välja selgitada ümbritsevate merealade sobivus tuuleenergeetika arendamiseks. |
