The British Geological Survey is the world's oldest national geological survey and commemorated its 175th anniversary in 2010.
 
The event was marked by a one-day science symposium on 28 September 2010.
 
The symposium showcased our world-class science and technologies, demonstrating their relevance, societal benefits and positive impacts in addressing 21st century challenges; including living with environmental change, energy and natural resource security, rising CO<sub>2</sub> emissions and geohazards.
 
* Peak metal: Scarcity of supply or scare story?
* Bronze Age Mediterraneans may have visited Stonehenge
* Modelling of Icelandic volcanic ash particles
 
The event was attended by influential stakeholders including representatives from government, industry, academia, international geological surveys, students and the national media.
 
Guest speakers included Dr Marcia McNutt, and [https://www.plymouth.ac.uk/staff/iain-stewart Professor Iain Stewart].
 
Britain's best-known natural history film-maker, [https://en.wikipedia.org/wiki/David_Attenborough Sir David Attenborough], featured in the panel discussion to close the symposium.

== Edward Greenly (1861–1951) ==
Campwaith pennaf [[Edward Greenly D.Sc.|Edward Greenly]] oedd cwblhau arolwg daearegol manwl o Ynys Môn. Cyhoeddwyd ''The Geology of Anglesey'' ([http://pubs.bgs.ac.uk/publications.html?pubID=B01782 Volume 1] and [http://pubs.bgs.ac.uk/publications.html?pubID=B06824 Volume 2]) mewn dwy gyfrol yn 1919 ac yna yn 1920 fap daearegol ar y raddfa un fodfedd i’r filltir. Er bod rhannau o’r gwaith wedi’u diweddaru yn ystod y degawdau dilynol, erys ei astudiaeth yn glasur o fri rhyngwladol.
=== Mapio Môn ===
Wrth fapio ynys Môn, gwnaeth Greenly ddefnydd mawr o syniadau tectonig a ddatblygodd wrth iddo fynd i’r afael â gwaith maes cynharach yn Ucheldiroedd yr Alban. Roedd tair prif broblem yn ei wynebu: prinder brigiadau da, yn enwedig mewn ardaloedd mewndirol allweddol bwysig; presenoldeb creigiau gorchuddiol clytiog yn cuddio yn aml y baslawr Cyn-Gambriaidd hŷn; a phresenoldeb toriadau tectonig megis ffawtiau a chylchfaoedd croesrym a oedd yn aml yn rhwystro’r gwaith o gydberthyn gwahanol ddilyniannau o greigiau. Chwaraeodd ei wraig Annie Greenly (Barnard gynt), a oedd yn rhannu ei ddiddordeb mewn daeareg a diwinyddiaeth, rôl hollbwysig drwy baratoi’r mynegai i’w gyfrol.
Ganed Greenly ym Mryste ac fe’i haddysgwyd yng Ngholeg Clifton. Bu’n fyfyriwr yng Ngholeg y Brifysgol, Llundain, cyn ymuno â’r Arolwg Daearegol yn 1889. Yn gyntaf, bu gofyn iddo baratoi arolwg o Ucheldiroedd gogledd-orllewin yr Alban. Daeth yn ffrind agos ac yn gydweithiwr i [[Benjamin Neeve Peach - biographical information|Ben Peach]] yr oedd ei archwiliadau wedi bod yn gyfrwng i ddatrys adeiledd cymhleth yr Alban (gan gynnwys adnabod a sylweddoli arwyddocâd Gwthiad Moine). Rhoddodd Greenly y gorau i’w waith gyda’r Arolwg yn 1895 er mwyn iddo, o’i ben a’i bastwn ei hun. roi cychwyn ar ei arolwg o Ynys Môn.
=== Cyfraniadau pwysig i ddaeareg ===
Yn gydnabyddiaeth am ei gyfraniadau pwysig i ddaeareg, cafodd Edward Greenly ei dderbyn yn aelod er anrhydedd o gymdeithasau daearegol Caeredin a Lerpwl, a Chymdeithas Hynafiaethwyr Môn. Dyfarnwyd iddo Fedal Lyell, fawr ei bri, y Gymdeithas Ddaearegol yn 1920, medal Cymdeithas Ddaearegol Lerpwl yn 1933 a doethuriaeth er anrhydedd Prifysgol Cymru yn 1920.
Ar y cyd â Howel Williams, cyhoeddodd [[Edward Greenly D.Sc.|Greenly]] ''Methods of Geological Surveying'' yn 1930 a’i hunangofiant ''A Hand through Time: Memories Romantic'' and ''Geological'' a ymddangosodd yn 1938. Bu farw ym Mangor yn 1951 ac yn briodol iawn fe’i claddwyd ym mynwent Llangristiolus, Ynys Môn. Mae ei fedd wedi’i gyfnodi’n Safle Geoamrywiaeth o Bwysigrwydd Rhanbarthol (RIGS).

BGS175: 175th Anniversary Science Symposium of the founding of the British Geological Survey, 28th September, Royal Institution, London

The British Geological Survey is the world's oldest national geological survey and commemorated its 175th anniversary in 2010.

The event was marked by a one-day science symposium on 28 September 2010.

The symposium showcased our world-class science and technologies, demonstrating their relevance, societal benefits and positive impacts in addressing 21st century challenges; including living with environmental change, energy and natural resource security, rising CO2 emissions and geohazards.

  • Peak metal: Scarcity of supply or scare story?
  • Bronze Age Mediterraneans may have visited Stonehenge
  • Modelling of Icelandic volcanic ash particles

The event was attended by influential stakeholders including representatives from government, industry, academia, international geological surveys, students and the national media.

Guest speakers included Dr Marcia McNutt, and Professor Iain Stewart.

Britain's best-known natural history film-maker, Sir David Attenborough, featured in the panel discussion to close the symposium.

Edward Greenly (1861–1951)

Campwaith pennaf Edward Greenly oedd cwblhau arolwg daearegol manwl o Ynys Môn. Cyhoeddwyd The Geology of Anglesey (Volume 1 and Volume 2) mewn dwy gyfrol yn 1919 ac yna yn 1920 fap daearegol ar y raddfa un fodfedd i’r filltir. Er bod rhannau o’r gwaith wedi’u diweddaru yn ystod y degawdau dilynol, erys ei astudiaeth yn glasur o fri rhyngwladol.

Mapio Môn

Wrth fapio ynys Môn, gwnaeth Greenly ddefnydd mawr o syniadau tectonig a ddatblygodd wrth iddo fynd i’r afael â gwaith maes cynharach yn Ucheldiroedd yr Alban. Roedd tair prif broblem yn ei wynebu: prinder brigiadau da, yn enwedig mewn ardaloedd mewndirol allweddol bwysig; presenoldeb creigiau gorchuddiol clytiog yn cuddio yn aml y baslawr Cyn-Gambriaidd hŷn; a phresenoldeb toriadau tectonig megis ffawtiau a chylchfaoedd croesrym a oedd yn aml yn rhwystro’r gwaith o gydberthyn gwahanol ddilyniannau o greigiau. Chwaraeodd ei wraig Annie Greenly (Barnard gynt), a oedd yn rhannu ei ddiddordeb mewn daeareg a diwinyddiaeth, rôl hollbwysig drwy baratoi’r mynegai i’w gyfrol.

Ganed Greenly ym Mryste ac fe’i haddysgwyd yng Ngholeg Clifton. Bu’n fyfyriwr yng Ngholeg y Brifysgol, Llundain, cyn ymuno â’r Arolwg Daearegol yn 1889. Yn gyntaf, bu gofyn iddo baratoi arolwg o Ucheldiroedd gogledd-orllewin yr Alban. Daeth yn ffrind agos ac yn gydweithiwr i Ben Peach yr oedd ei archwiliadau wedi bod yn gyfrwng i ddatrys adeiledd cymhleth yr Alban (gan gynnwys adnabod a sylweddoli arwyddocâd Gwthiad Moine). Rhoddodd Greenly y gorau i’w waith gyda’r Arolwg yn 1895 er mwyn iddo, o’i ben a’i bastwn ei hun. roi cychwyn ar ei arolwg o Ynys Môn.

Cyfraniadau pwysig i ddaeareg

Yn gydnabyddiaeth am ei gyfraniadau pwysig i ddaeareg, cafodd Edward Greenly ei dderbyn yn aelod er anrhydedd o gymdeithasau daearegol Caeredin a Lerpwl, a Chymdeithas Hynafiaethwyr Môn. Dyfarnwyd iddo Fedal Lyell, fawr ei bri, y Gymdeithas Ddaearegol yn 1920, medal Cymdeithas Ddaearegol Lerpwl yn 1933 a doethuriaeth er anrhydedd Prifysgol Cymru yn 1920.

Ar y cyd â Howel Williams, cyhoeddodd Greenly Methods of Geological Surveying yn 1930 a’i hunangofiant A Hand through Time: Memories Romantic and Geological a ymddangosodd yn 1938. Bu farw ym Mangor yn 1951 ac yn briodol iawn fe’i claddwyd ym mynwent Llangristiolus, Ynys Môn. Mae ei fedd wedi’i gyfnodi’n Safle Geoamrywiaeth o Bwysigrwydd Rhanbarthol (RIGS).
