Thursday's [Obladi-Oblada] is all about the various episodes and happenings that occur in our daily lives.
Write a diary entry to yourself on [Scribble Scribble] We'll introduce various news topics that are not really making the headlines…but are interesting to know with [M. #Scribble Scribble Don't you think we should take some time to reorganize our thoughts at least one day in the week?
Lisa Poisso and Robin Torres are experienced gamers and real-life mamas -- and just as we don't want our precious babies to be the ones kicking and wailing on the floor of the checkout lane next to the candy, neither do we want you to become known as That Guy on your realm.
Throughout history, there have been more songs written about love than any topic.
C) dates with the Ramped Pyr Ox (RP) radiocarbon dating technique within a single sediment core, and we confirm the utility for the latter constructing chronologies of high latitude, Holocene marine margin sediment successions.
Historically, the heavily detrital nature of Antarctic margin sedimentary organic material and lack of carbonate preservation have made these sediments difficult to date accurately.
Here, we use archived cores with existing foraminiferal ages to compare with RP dates at equal or similar depth intervals.
The lowest temperature RP splits were integrated over narrower intervals than in previous studies to reduce the amount of mixing with older, more thermochemically stable end-members during pyrolytic decomposition.
Ages of the low-temperature RP splits coincide with their corresponding carbonate counterparts, suggesting that the RP C dating.
The rarity of calcareous material in most Antarctic sediments often obligates the use of the bulk acid insoluble organic (AIO) fraction of the sediment, which can be problematic because of contamination by older carbon.
The bulk AIO C ages, which are calculated using the weighted arithmetic mean of all RP splits of individual samples, show that age reversals and biases can occur using bulk AIO dates for age models because of variable proportions of pre-aged organic matter down-core.
The application of the RP dating method can reduce these effects to produce a more reliable chronology that is statistically identical to the foraminiferal dating chronology.
