Jäätalvi 1965/66 oli Suomen merialueilla keskinkertaista kovempi. Se alkoi aikaisin ja kesti varsinkin pohjoisilla merialueilla myöhään. Myös Tanskan salmiin ja eteläi- selle Itämerelle muodostui jäätä, mutta jää- talvi jäi suhteellisen lyhyeksi.

Jäänmuodostus alkoi marraskuun puoli- välissä ja se oli alusta alkaen nopeata. Niin- pä Perämeren ulapan peittyminen ensi ker- ran jäähän joulukuun 24 päivänä ja lopulli- sesti joulukuun 31 päivänä oli huomatta- vasti keskinkertaista aikaisempi tapah- tuma. Selkämeri peittyi jäähän tammi- kuun 18 päivänä ja Suomenlahdella oli run- saasti liikkuvaa jäätä. Erittäin vaikeaksi jäätilanne muodostui helmikuun alkupuo- lella, jolloin itätuuli kuljetti Suomenlah- delta paksuja lauttoja länteen päin ja poh- joisella Itämerellä jään reuna oli noin 75 mpk Utön eteläpuolella. Näihin aikoihin muodostui myös Tanskan salmiin ja Saksan rannikolle jäätä. Laajin jäätilanne, 370 000 km2, saavutettiin helmikuun 22 päivänä.

Jään taantuminen ja sulaminen Tanskan salmissa ja eteläisellä Itämerellä tapahtui nopeasti, mutta pohjoisella Itämerellä oli vielä maaliskuun lopussa leveä vyöhyke paksua jäätä. Vasta huhtikuun alussa mai- nittu jääkenttä hajaantui. Selkämeren Suo- men puoleiselle rannikolle muodostui huhti- kuun alussa leveä avoin alue, joka teki tilan- teen meriliikenteellisesti helpoksi. Jäiden sulaminen viivästyi kuitenkin ja Ahvenan- meren pohjoispuolella oli paksuja lauttoja vielä toukokuun puolivälissä. Myös Perä- merellä jään sulaminen oli hidasta viimeis- ten lauttojen hajaantuessa vasta kesäkuun alussa.

The ice winter 1965/66 was more severe than average in the Finnish sea areas. It began early and lasted long especially in the northernmost areas. Ice formed even in the Danish Sounds and in the Southern Baltic.

There, however, the ice winter was rela- tively short.

The formation of ice started in the middle of November and ice formed rapidly from the very beginning. Thus the Bay of Bothnia was covered by the first ice on December 24, and on December 31 it re- ceived the permanent ice cover. This hap- pened remarkably earlier than usually. Ice covered the Sea of Bothnia on January 18, and plenty of pack ice was found in the Gulf of Finland. The ice situation turned very difficult in early February, when thick ice floes were carried westward from the Gulf of Finland by the east wind and the ice limit on the Northern Baltic lay about 75 nautical miles south of Utö. About that time ice formed also in the Danish Sounds and along the German coast. The largest extent of the ice cover (370 000 km2) was attained on February 22.

Ice receded and melted rapidly in the Danish Sounds and in the Southern Baltic, but in the Northern Baltic a wide belt of thick ice occured as late as the end of March.

This ice field did not spread out until early April. In the beginning of April a wide open area formed along the Finnish coast of the Sea of Bothnia making the ice situation easy for navigation. The melting of ice was delayed, however, and thick ice floes were still found north of the Åland Sea in the middle of May. Ice melted slowly also in the Bay of Bothnia, where the last ice floes disappeared in early June.

Jäätalvesta 1966/67 muodostui keskinker- taista hieman helpompi. Se alkoi tosin aikaisin ja alkukehitys oli nopeata. Mutta keskitalvi oli leuto eikä jäätä muodostunut sanottavasti tammikuun jälkeen. Tämä py- sytti tilanteen lounaisrannikollamme taval- lista helpompana. Perämerellä sensijaan jää paksuuntui huomattavasti, mutta keväällä avautuneet railot helpottivat meriliikenteen sujumista.

Ensijäätymisiä sattui jo loka- ja marras- kuussa, mutta varsinainen jäätalvi alkoi vasta joulukuun 7 päivänä. Uutta jäätä muodostui nopeasti ja Perämeren ulappa oli kokonaan jäässä tammikuun 10 päivänä.

Vaikeita ahtautumia muodostui meren poh- joisosiin erikoisesti Kemin ulostuloväylälle.

Jäänmuodostus jatkui tammikuussa ja tammikuun lopussa olivat Selkämeri, Ah- venanmeri ja Suomenlahti peittyneet koko- naan jäähän. Pohjoisella Itämerellä ajo- jäätä ulottui lähes 30 meripeninkulmaa Utön ulkopuolelle. Tämä jäi talven laajim- maksi, ollen se 190 000 km2.

Keskitalvelle ominaisia pakkasia ei tänä talvena tullut ja jään taantuminen pääsi al- kamaan keskimääräistä aikaisemmin. Suo- menlanden itäosassa samoinkuin Selkä- merellä olleet ahtojään vyöhykkeet irto- sivat ja hajaantuivat suhteellisen myöhään huhtikuussa. Perämerelle avautuneet pit- kät, rannikon suuntaiset railot edistivät meriliikenteen sujumista, vaikka muualla jääkentät olivat vielä paksuja. Viimeiset jäät Suomen rannikolta hävisivät touko- kuun 27 päivänä, Ruotsin puolelta, Malöre- fin tienoilta kesäkuun alussa.

The ice winter 1966/67 was somewhat easier than average. It certainly bagan early and developed rapidly in the beginning, but the midwinter remained mild and new ice did not form after January. Thus the ice situa- tion along the southwest coast of Finland was easier than usual. In the Bay of Bothnia, however, ice grew much thicker, but the shore leads that opened in late winter made navigation easier.

The first ice formed as early as in late October and early November, but the real ice winter did not come until December 7.

New ice formed rapidly, and on January 10 all the Bay of Bothnia was covered by ice.

In the northernmost Bay of Bothnia trou- blesome ridges had formed outside Kemi.

The formation of ice continued in Janua- ry, and at the end of January ice covered wholly the Sea of Bothnia, the Åland Sea and the Gulf of Finland. In the Northern Baltic the pack ice extended for almost 30 nautical miles outside Utö. This was the largest extent of ice (190 000 km2) during this winter.

Cold periods, which characterize an ordi- nary midwinter, did not occur this year, and ice started to recede earlier than usual.

The belts of ridged ice on the eastern Gulf

of Finland and on the Sea of Bothnia broke

up and spread out rather late in April. All-

though the ice cover on the Bay of Bothnia

still remained thick, navigation became

easier because of the long shore leads that

had opened along the coast. The last ice

was reported on the Finnish coast on May

27 and on the Swedish coast near Malören

in early June.

Jäätalven 1967/68 vaikeusastetta on pidet- tävä keskinkertaisena. Selkämerellä Suo- men rannikolle syntyneiden ahtautumien vuoksi tilanne siellä oli vaikea, mutta Saaristomerellä ja Suomenlahdella se pysyi suhteellisen helppona.

Talvi alkoi joulukuun alussa, siis melko myöhään. Mutta ensimmäiset pakkasjaksot olivat kovia ja jäänmuodostus niiden ai- kana nopeata. Siten tammikuun alussa ta- pahtunut Perämeren ulapan peittyminen jäähän samoin kuin Suomenlahdella jää- peitteen leviäminen yli sen itä- ja keski- osien vastasi ajankohdaltaan keskimääräi- siä oloja.

Tammikuussa jäänmuodostus oli taasen hitaampaa, mutta helmikuun alussa Selkä- meri peittyi kokonaan jäähän, samoin poh- joinen Itämeri Bogskärin kareja myöten.

Tämä tilanne tulikin laajimmaksi, 215 km2 ja kesti sellaisena helmikuun 25 päivän tie- noille.

Jään taantuminen Suomenlahdella sujui nopeasti ja jäiden sulaminen tapahtui keski- määräistä aikaisemmin. Sensijaan Selkä- meren rannikolla jää länsituulten vaiku- tuksesta ahtautui, ja tällaiset paksut kentät pysyivät paikoillaan huhtikuun loppuun saakka. Perämerellä ulapan jääkenttien rik- koutuminen ja sulaminen pääsi vauhtiin vasta huhtikuun puolivälissä. Toukokuun puolivälissä jäät ajautuivat Ruotsin puo- lelle, joten Suomen rannikko vapautui jäistä keskimääräistä aikaisemmin.

The ice winter 1967/68 was close to the normal. Ridges along the Finnish coast made the ice situation difficult in the Sea of Bothnia, whereas the situation in the Archipelago Sea and in the Gulf of Finland remained rather easy.

The winter began relatively late, in the beginning of December, but the first cold periods were very intense and caused the rapid formation of ice. Thus the ice covered the Bay of Bothnia and the eastern and middle parts of the Gulf of Finland in early January, which was close to average.

In January the formation of ice was very slow, but in early February ice already covered the Sea of Bothnia and the North- ern Baltic to the Bogskär lighthouse. This was the most extensive ice cover of the winter (215 000 km2), and this ice situation remained unchanged till February 25.

The ice on the Gulf of Finland receded

rapidly and the melting occurred earlier

than usual. Wind, however, pressed the ice

against the coast of the Sea of Bothnia and

thick ice-ridges lay still up to the end of

April. The ice cover on the Bay of Bothnia

did neither break nor melt until the middle

of April. At that time ice drifted towards

the Swedish coast, and thus the Finnish

coast become ice-free earlier than usual.

Jäätalvi oli keskinkertaista hieman vai- keampi, erikoisesti sen kestoaika oli pitkä.

Talvi alkoi jo poikkeuksellisen aikaisin lokakuun puolivälissä, jolloin Perämeren pohjoisosaan muodostui kapea jäävyöhyke.

Jääpeite ei kuitenkaan sanottavasti laajen- tunut marras—joulukuussa. Tammikuun alusta alkaen vallitsi kovia, mutta yleensä lyhyitä pakkasjaksoja. Helmikuussa val- litsi jo pitempikin yhtäjaksoinen pakkanen, jonka aikana jäänmuodostus oli suhteellisen nopeata. Maaliskuun 3 päivänä saavutettiin talven laajin jäätilanne, 260 000 km2, jol- loin Perämeri, Selkämeri ja Suomenlahti olivat kauttaaltaan jäässä. Pohjoisella Itä- merellä jää ulottui tällöin noin 65 mpk Utön eteläpuolelle.

Maaliskuun aikana kovien yöpakkasten vaikutuksesta jäät edelleen paksuuntuivat, jolloin tilanne varsinkin Selkämerellä vai- keutui.

Jäiden sulaminen ja taantuminen siirtyi melko myöhäiseen ajankohtaan, mutta tuulien vaikutuksesta ulapan jääkentät Suomenlahdella ja Selkämerellä osittain ha-

jaantuivat, osittain ajautuivat Ruotsin ran- nikolle. Perämerellä ulappa pysyi ehjänä huhtikuun lopulle saakka. Kun lisäksi jää Suomen puoleisella merialueella oli melko tasaista, tämä helpotti pohjoisten satamien avaamista. Viimeiset jäät Perämerellä ha- vaittiin kesäkuun 12 päivänä.

The ice winter 1968/69 was somewhat more difficult than the average, especially in regard to the duration.

The winter began exceptionally early in the middle of October, when a narrow belt of ice formed in the northernmost part of the Bay of Bothnia. The ice cover did not, however, spread to any noteworthy extent during November and December. From the beginning of January on intense, though generally short cold periods, did occur. In February the cold weather prevailed longer and new ice formed rather rapidly. On March 3 the largest extent of ice (260 000 km2) was attained; the Bay of Bothnia, the Sea of Bothnia, and the Gulf of Finland were totally covered by ice, and the ice on the Northern Baltic extended for about 65 nautical miles south of Utö.

In March severe night frosts made the ice grow thicker, and the ice situation became more difficult, especially in the Sea of Bothnia.

Thus the receding and melting of ice was

delayed. In the Gulf of Finland and in the

Sea of Bothnia, however, the winds partly

spread out the ice cover, partly drifted it

against the Swedish coast. The ice on the

Bay of Bothnia remained unbroken until

the end of April. Opening the northern

harbours for navigation became easier as

the ice along the Finnish coast was fairly

Ievel. The last ice on the Bay of Bothnia was

reported on June 12.

Jäätalvi 1969/70 on laskettava ankariin tal- viin kuuluvaksi. Se oli kaikilla merialueilla pitkä ja jä än ulottuvuus laaja. Jään paksuus ei talven aikana kuitenkaan kasvanut ko- vin suureksi ja pahimmat ahtautumat muo- dostuivat Ruotsin rannikolle.

Talven alkaminen tapahtui marraskuussa keskimääräisiä ajankohtia noudattaen. Kui- tenkin joulukuun puolivälistä helmikuun loppuun kestänyt melkein yhtämittainen pakkaskausi sai aikaan runsaan jäänmuo- dostuksen. Talven laajin jäätilanne, 370 000 km2, saavutettiin helmikuun 19 päivänä, jol- loin Perämeri, Selkämeri, Suomenlahti ja pohjoinen Itämeri Gotlantia myöten olivat jäässä. Myös Tanskan salmissa ja eteläisen Itämeren ranta-alueilla oli jäätä. Jää oli kuitenkin suhteellisen ohutta ja tasaista.

Helmikuun 20 päivänä alkoi jään taan- tuminen Tanskan salmissa ja eteläisellä Itä- merellä. Pohjoisella Itämerellä ja Selkä- merellä tuulet painoivat jäitä kohden Ruot- sin rannikkoa, missä koko kevään tilanne meriliikenteellisesti oli vaikea. Suomen rannikolla tilanne oli helpompi, vaikkakin sulaminen oli hidasta. Perämeren melko tasaisena pysynyt jääpeite pysyi rikkoutu- mattomana melko myöhäiseen ajankohtaan ja sen sulaminen kesti kesäkuun alkuun saakka.

The ice winter 1969/70 was rather severe. It lasted long in all sea areas and the amount of ice became great. However, ice field on the Finnish side remained rather level, and the most troublesome ridges formed along the Swedish coast.

The winter began in due course in No- vember, but then the formation of ice increased greatly during an almost con- tinuous cold period from the middle of December to the end of February. The largest extent of ice (370 000 km"-) was attained on February 19, when ice covered the Gulf of Bothnia, the Sea of Bothnia, the Gulf of Finland and the Northern Baltic to Gotland. Ice formed also on the Danish Sounds and on the coast of the Southern Baltic. The ice remained rather level in these areas.

On February 20 the ice on the Danish Sounds and the Southern Baltic began to recede. In the Northern Baltic and the Sea of Bothnia the wind pressed the ice against the Swedish coast, where the ice situation was difficult throughout the spring. The level ice cover on the Bay of Bothnia remained unbroken to late spring, and the melting was not brought to an end until the beginning of June.

Jäätalvi 1965/66 oli Suomen merialueilla keskinkertaista kovempi. Se alkoi aikaisin ja kesti varsinkin pohjoisilla merialueilla myöhään. Myös Tanskan salmiin ja eteläi- selle Itämerelle muodostui jäätä, mutta jää- talvi jäi suhteellisen lyhyeksi.

The ice winter 1965/66 was more severe than average in the Finnish sea areas. It began early and lasted long especially in the northernmost areas. Ice formed even in the Danish Sounds and in the Southern Baltic.

There, however, the ice winter was rela- tively short.

Ice receded and melted rapidly in the Danish Sounds and in the Southern Baltic, but in the Northern Baltic a wide belt of thick ice occured as late as the end of March.

Kartta 2. Jään laajin ulottuvuus 1966/67.

Chart 2. The maximum extent of ice cover 196667.

Ensijäätymisiä sattui jo loka- ja marras- kuussa, mutta varsinainen jäätalvi alkoi vasta joulukuun 7 päivänä. Uutta jäätä muodostui nopeasti ja Perämeren ulappa oli kokonaan jäässä tammikuun 10 päivänä.

Vaikeita ahtautumia muodostui meren poh- joisosiin erikoisesti Kemin ulostuloväylälle.

Jäänmuodostus jatkui tammikuussa ja tammikuun lopussa olivat Selkämeri, Ah- venanmeri ja Suomenlahti peittyneet koko- naan jäähän. Pohjoisella Itämerellä ajo- jäätä ulottui lähes 30 meripeninkulmaa Utön ulkopuolelle. Tämä jäi talven laajim- maksi, ollen se 190 000 km2.

The first ice formed as early as in late October and early November, but the real ice winter did not come until December 7.

New ice formed rapidly, and on January 10 all the Bay of Bothnia was covered by ice.

In the northernmost Bay of Bothnia trou- blesome ridges had formed outside Kemi.

Cold periods, which characterize an ordi- nary midwinter, did not occur this year, and ice started to recede earlier than usual.

The belts of ridged ice on the eastern Gulf

of Finland and on the Sea of Bothnia broke

up and spread out rather late in April. All-

though the ice cover on the Bay of Bothnia

still remained thick, navigation became

easier because of the long shore leads that

had opened along the coast. The last ice

was reported on the Finnish coast on May

27 and on the Swedish coast near Malören

in early June.

Chart 3. The maximum extent oj ice cover 1967168.

Jäätalven 1967/68 vaikeusastetta on pidet- tävä keskinkertaisena. Selkämerellä Suo- men rannikolle syntyneiden ahtautumien vuoksi tilanne siellä oli vaikea, mutta Saaristomerellä ja Suomenlahdella se pysyi suhteellisen helppona.

Tammikuussa jäänmuodostus oli taasen hitaampaa, mutta helmikuun alussa Selkä- meri peittyi kokonaan jäähän, samoin poh- joinen Itämeri Bogskärin kareja myöten.

Tämä tilanne tulikin laajimmaksi, 215 km2 ja kesti sellaisena helmikuun 25 päivän tie- noille.

The ice winter 1967/68 was close to the normal. Ridges along the Finnish coast made the ice situation difficult in the Sea of Bothnia, whereas the situation in the Archipelago Sea and in the Gulf of Finland remained rather easy.

The winter began relatively late, in the beginning of December, but the first cold periods were very intense and caused the rapid formation of ice. Thus the ice covered the Bay of Bothnia and the eastern and middle parts of the Gulf of Finland in early January, which was close to average.

In January the formation of ice was very slow, but in early February ice already covered the Sea of Bothnia and the North- ern Baltic to the Bogskär lighthouse. This was the most extensive ice cover of the winter (215 000 km2), and this ice situation remained unchanged till February 25.

The ice on the Gulf of Finland receded
