[4] On 8 September 2023, following a series of monsoons, part of the Chonburi provincial coast experienced a plankton boom killing off numerous marine life such as ponyfishes, crabs, pufferfishes, and tilapias.

In early November 2020, an almost perfectly preserved skeleton of a Bryde's whale was discovered on the coast of Ban Phaeo district, Samut Sakhon.

[8] The National University of Singapore said that the skeleton added to evidence of significant sea level changes around 6,000 to 3,000 years ago in the Bay of Bangkok.

[12] The coastline of the Bay of Bangkok is occupied by several major cities such as Hua Hin, Pattaya, Si Racha and Laem Chabang.

[17] Koh Lan is a popular island off Pattaya in the Bay of Bangkok, attracting around 2,500 visitors each day during Thailand's peak season before the COVID-19 pandemic.

Its cost was estimated to be around ฿900 billion in 2020,[22] while its length around 80 to 100 km, making it longer than the Hong Kong–Zhuhai–Macau Bridge, the current longest sea crossing.

[25] The project has been proposed with a land bridge between Chumphon and Ranong across the Kra Isthmus,[23] which was approved by the cabinet of Srettha Thavisin on 16 October 2023.
