The Transcontinental Arch refers to the islands of North America which extended from New Mexico to Minnesota and the Great Lakes region.[1][2] These islands were present during the Sauk sequence, the earliest cratonic sequence. As a result of the Sauk sequence, epeiric seas covered most of North America, leaving only the craton of the Canadian Shield and the Transcontinental Arch islands exposed.
Climate-driven depopulation and adaptation realities in America’s coastal ground zero
With global temperatures poised to exceed the 1.5 °C Paris Agreement threshold—a level that triggered substantial ice-sheet collapse during the Last Interglacial—low-elevation coastal zones face sea-level commitments far beyond current planning horizons. With this geological frame of reference, we examine the impact of sea-level rise on what may be the most physically vulnerable coastal zone in the world using prehistoric and contemporary patterns of human mobility. We highlight the positive aspects of the recently commenced out-migration in this region and argue that the fate of communities landwards of this coastal zone will be decided in the next few decades.
Pacific kelp forests are far older than we thought - Berkeley News
The unique underwater kelp forests that line the Pacific Coast support a varied ecosystem that was thought to have evolved along with the kelp over the past 14 million years. But a new study shows that kelp flourished off the Northwest Coast more than 32 million years ago, long before the appearance of modern groups […]

The Chesapeake Slave Trade:Regional Patterns, African Origins, and Some Implications | History Cooperative
THE movement of peoples from the Old World to the New and the resulting transfers or transformations of homeland cultures in new physical and social environments has been a central theme of early American history. Overwhelmingly, historians have written on the transfers of peoples from sixteenth- through eighteenth-century Europe and sub-Saharan Africa to various American destinations in isolation from one another. When these two contemporary migration flows are considered together, sheer numbers demonstrate that, up to 1776, the majority of men, women, and children transported from the Old World to British North America were, to varying degrees, unfree. And increasingly throughout most of the eighteenth century, those migrants came from Africa and were permanently enslaved.

In May 1976 a Satawalese master navigator named Mau Piailug stood on the deck of a double-hulled Polynesian canoe in Honolua Bay, Maui, and prepared to sail to Tahiti. Sans compass, chronometer, and chart. The canoe was Hōkūleʻa, a replica of the voyaging craft that had carried Polynesians across the Pacific a thousand years earlier. Over the next thirty-four days Piailug would navigate her about two thousand three hundred nautical miles south-southeast to Papeete using the rising and setting positions of stars, the shape of ocean swells refracted off islands beyond the horizon, the colour of the water at dusk, and the behaviour of terns returning to land at evening.

Aboriginal Memories of Inundation of the Australian Coast Dating from More than 7000 Years Ago (Australian Geographer)
"Some stories belonging to Australian Aboriginal groups tell of a time when the former coastline of mainland Australia was inundated by rising sea level. Stories are presented from 21 locations from every part of this coastline. In most instances it is plausible to assume that these stories refer to events that occurred more than about 7000 years ago, the approximate time at which sea level reached its present level around Australia. They therefore provide empirical corroboration of postglacial sea-level rise. For each of the 21 locations, the minimum water depth (below present sea level) needed for the details of the particular group of local-area stories to be true is calculated. This is then compared with the sea-level envelope for Australia (Lewis et al., Quaternary Science Reviews, 2013) and maximum and minimum ages for the most recent time that these details could have been observed are calculated. This method of dating Aboriginal stories show that they appear to have endured since 7250-13,070 cal yr BP (5300-11,120 BC). The implications of this extraordinary longevity of oral traditions are discussed, including those aspects of Aboriginal culture that ensured effective transgenerational communication and the possibility that traditions of comparable antiquity may exist in similar cultures."
