Suggest that the increased flux of GrIS icebergs as inferred from NorthĪtlantic proxy records could have been triggered, or intensified, by peaks in Oceanically induced ice-volume contributions above 1 m sea level equivalent (SLE). Strongly influenced by oceanic changes on millennial timescales, leading to We show that the GrIS evolution during the LGP could have been Melting at millennial timescales is a direct result of an increase in basal Since in our model theĪtmospheric forcing follows orbital variations only, the increase in total To do so, we use a three-dimensional hybrid ice-sheet–shelf model forcedīy subsurface oceanic temperature fluctuations, assumed to increase duringĭ-O stadials and decrease during D-O interstadials. Variability on the GrIS evolution from the last interglacial to the presentĭay. Here we assess the effect of millennial-scale oceanic Therefore oceanic temperatureįluctuations on millennial timescales could have had a non-negligible impact During the LGP, the GrIS expandedĪs far as the continental shelf break and was thus more directly exposed to Meridional Overturning Circulation (AMOC). Modelling studies robustly links these to reorganisations of the Atlantic Their ultimate cause is still debated, evidence from both proxy data and Last glacial period (LGP) known as Dansgaard-Oeschger (D-O) events. Have an iceberg shot you'd like to share? Go to IcebergFinder.Temperature reconstructions from Greenland ice-sheet (GrIS) iceĬores indicate the occurrence of more than 20 abrupt warmings during the Thankfully, Phil was able to capture it in all its glory. This iceberg was the crown jewel of the Bonavista area this spring. It’s impossible to not be taken back when you can look out your window at a 10,000-year old ice cathedral in your front yard. You’d think we get used to views like these, but we don’t. Elizabeth captured the perspective of this behemoth perfectly as it towered over a small community near Twillingate. Here’s a double feature from Dru Kennedy and Corwin Roberts, including a photobomb appearance from some other frequent visitors. With dozens of photos to choose from, we couldn’t pick just one. TritonĪ massive iceberg called Triton home for over a month this spring providing creators with ample opportunity to capture. Anthony to witness this beautiful berg bask in the glow of spring golden hour, within an arm’s reach of shore. Locals and travellers alike gathered at Fox Point Light Station in St. What more could you ask for from Great Brehat. Great BrehatĪ great sunset and a great iceberg make for a great photo. They nicknamed this one “The Runway” due to its size and shape. The residents of Quirpon have seen icebergs of all shapes and sizes over the years, so for them to call an iceberg big it must truly be big. Tom managed to capture this beauty as it snuck past Battle Harbour. Battle HarbourĪs icebergs break off from Greenland they follow the Labrador Current down along the east coast of Labrador, usually too far offshore to view. If you are as happy as we are to see them again, then read on, here are our favourite photos from an exciting 2022 iceberg season in Newfoundland and Labrador. While the last couple of years haven’t produced as many photo opportunities as we’d like, we were thrilled to see quite a few frosty giants drift past our shores this year. After all, if you were 10,000 years old, you’d take your time too. Around here, things move at a different pace and that suits our icebergs just fine.
