Energy giant BP reported a significant fall in first-quarter net profit on Tuesday, as oil prices continue to dive amid intensifying concerns about the coronavirus crisis and dwindling storage capacity. The U. BP’s results come shortly after a historic plunge in oil prices. The May contract of U. West Texas Intermediate plunged below zero to trade in negative territory for the first time in history last week. Trading volume was thin given it was the day before the contract’s expiration date, but the move lower was unprecedented nonetheless.

A date expressed as ”11, BP” means 11, years before the present, using as the benchmark. Dates given as BP—especially if determined by.

For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites. There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating.

Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years. Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.

On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations. These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well. This is the only type of techniques that can help clarifying the actual age of an object.

The timing of the first entry of humans into North America is still hotly debated within the scientific community. Excavations conducted at Bluefish Caves Yukon Territory from to yielded a series of radiocarbon dates that led archaeologists to propose that the initial dispersal of human groups into Eastern Beringia Alaska and the Yukon Territory occurred during the Last Glacial Maximum LGM. This hypothesis proved highly controversial in the absence of other sites of similar age and concerns about the stratigraphy and anthropogenic signature of the bone assemblages that yielded the dates.

The weight of the available archaeological evidence suggests that the first peopling of North America occurred ca. Here, we report new AMS radiocarbon dates obtained on cut-marked bone samples identified during a comprehensive taphonomic analysis of the Bluefish Caves fauna.

Beringia, a vast region stretching from the Lena River in Siberia to the Mackenzie River in the Yukon Territory [ 1 , 2 ], is thought to have played a pivotal role in the initial dispersal of human populations from Asia to North America. The exact timing of the initial dispersal remains uncertain, however.

The initials BP or bp and rarely B. While BP is also used generally as an imprecise estimate of an age of an object or event, the use of it in science was made necessary by the quirks of the radiocarbon methodology. Radiocarbon dating was invented in the late ‘s, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years.

Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons such as the invention of iron smelting , the Industrial Revolution , and the invention of the combustion engine.

For those researchers working in the field of human history, the eruption dating back to years BP (Before Present; “present” indicates c.

Current protocols for ancient DNA and radiocarbon analysis of ancient bones and teeth call for multiple destructive samplings of a given specimen, thereby increasing the extent of undesirable damage to precious archaeological material.

Here we present a method that makes it possible to obtain both ancient DNA sequences and radiocarbon dates from the same sample material. This is achieved by releasing DNA from the bone matrix through incubation with either EDTA or phosphate buffer prior to complete demineralization and collagen extraction utilizing the acid-base-acid-gelatinization and ultrafiltration procedure established in most radiocarbon dating laboratories.

We also detect no skews in radiocarbon dates compared to untreated samples. Over the past 70 years, radiocarbon dating has become an important tool for archaeology due to its precision in dating organic material up to approx. More recently, advances in DNA sequencing technology have enabled the generation of genome-wide sequence data from hundreds of ancient remains, especially those of ancient humans 5 , 6 , 7 , 8 and their extinct archaic relatives 9 , 10 , 11 , providing insights into the history of human groups, their dispersals and interactions.

In contrast to AMS radiocarbon dating, genetic analysis of ancient bones and teeth is often feasible even from small amounts of sample material.

Common questions about dates

Deepwater Horizon oil spill , also called Gulf of Mexico oil spill , largest marine oil spill in history, caused by an April 20, , explosion on the Deepwater Horizon oil rig—located in the Gulf of Mexico , approximately 41 miles 66 km off the coast of Louisiana —and its subsequent sinking on April The Deepwater Horizon rig, owned and operated by offshore-oil-drilling company Transocean and leased by oil company BP , was situated in the Macondo oil prospect in the Mississippi Canyon, a valley in the continental shelf.

The oil well over which it was positioned was located on the seabed 4, feet 1, metres below the surface and extended approximately 18, feet 5, metres into the rock. On the night of April 20 a surge of natural gas blasted through a concrete core recently installed by contractor Halliburton in order to seal the well for later use.

It later emerged through documents released by Wikileaks that a similar incident had occurred on a BP-owned rig in the Caspian Sea in September

BP: How Do Archaeologists Count Backward Into the Past?

Before Present BP years is a time scale used mainly in archaeology , geology , and other scientific disciplines to specify when events occurred prior to the origin of practical radiocarbon dating in the s. Because the “present” time changes, standard practice is to use 1 January as the commencement date epoch of the age scale.

The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy.
